refactor: remove vendor directory to use Go proxy service

Removes local vendor directory in favor of Go module proxy for cleaner
repository and improved dependency management. Dependencies will now be
fetched automatically from proxy.golang.org during builds.

 # Open Accounting Server
 
+Open Accounting Server is a modern financial accounting system built with Go, featuring GORM integration, Viper configuration management, and Docker support.
+
+## Features
+
+- **GORM Integration**: Modern ORM with SQLite and MySQL support
+- **Viper Configuration**: Flexible config management with environment variables
+- **Modular Storage**: S3-compatible attachment storage (Local, AWS S3, Backblaze B2, Cloudflare R2, MinIO)
+- **Docker Ready**: Containerized deployment with multi-stage builds
+- **SQLite Support**: Easy local development and testing
+- **Security**: Environment variable support for sensitive data
+
 ## Prerequisites
 
-1. Go 1.8+
-2. MySQL 5.7+
+- **Go 1.24+** (updated from 1.8+)
+- **SQLite** (for development) or **MySQL 5.7+** (for production)
+- **Docker** (optional, for containerized deployment)
+- **Just** (optional, for build automation)
 
-## Database setup
+## Quick Start
 
-Use schema.sql and indexes.sql to create a MySQL database to store Open Accounting data.
+### Using Just (Recommended)
+
+```bash
+# Setup development environment
+just dev-setup
+
+# Run in development mode
+just run-dev
+
+# Build and run with Docker
+just docker-run
+```
+
+### Manual Setup
+
+```bash
+# Install dependencies
+go mod download
+
+# Run with SQLite (development)
+OA_DATABASE_DRIVER=sqlite ./server
+
+# Run with MySQL (production)
+OA_DATABASE_DRIVER=mysql OA_PASSWORD=secret ./server
+```
 
 ## Configuration
 
-Copy config.json.sample to config.json and edit to match your information.
+The server now uses **Viper** for advanced configuration management with multiple sources:
 
-## Run
+### Configuration Sources (in order of precedence)
 
-`go run core/server.go`
+1. **Environment Variables** (highest priority)
+2. **Config Files**: `config.json`, `config.yaml`, `config.toml`
+3. **Default Values** (lowest priority)
 
-## Build
+### Config File Locations
 
-`go build core/server.go`
+- `./config.json` (current directory)
+- `/etc/openaccounting/config.json`
+- `~/.openaccounting/config.json`
+
+### Environment Variables

+              key: db-password
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Config file not found**: The server will use environment variables and defaults if no config file is found
+2. **Database connection failed**: Check your database credentials and connectivity
+3. **Permission denied**: Ensure proper file permissions for SQLite database files
+
+### Debug Mode
+
+```bash
+# Enable verbose logging
+OA_LOG_LEVEL=debug ./server
+
+# Check configuration
+just config-help
+```
+
+### Health Checks
+
+```bash
+# Application health
+curl http://localhost:8080/api/v1/health
+
+# Docker health check
+docker inspect --format='{{.State.Health.Status}}' container_name
+```
+
+## Migration from Legacy Setup
+
+The server maintains backward compatibility with existing `config.json` files while adding Viper features:
+
+1. Existing `config.json` files continue to work
+2. Add environment variables for sensitive data
+3. Use SQLite for easier local development
+4. Leverage Docker for production deployments

+# Modular Storage System
+
+The OpenAccounting server now supports multiple storage backends for file attachments. This allows you to choose between local filesystem storage for simple deployments or cloud storage for production/multi-user environments.
+
+## Supported Storage Backends
+
+### 1. Local Filesystem Storage
+Perfect for self-hosted deployments or development environments.
+
+**Configuration:**
+```json
+{
+  "storage": {
+    "backend": "local",
+    "local": {
+      "root_dir": "./uploads",
+      "base_url": "https://yourapp.com/files"
+    }
+  }
+}
+```
+
+**Environment Variables:**
+```bash
+OA_STORAGE_BACKEND=local
+OA_STORAGE_LOCAL_ROOT_DIR=./uploads
+OA_STORAGE_LOCAL_BASE_URL=https://yourapp.com/files
+```
+
+### 2. Amazon S3 Storage  
+Reliable cloud storage for production deployments.
+
+**Configuration:**
+```json
+{
+  "storage": {
+    "backend": "s3",
+    "s3": {
+      "region": "us-east-1",
+      "bucket": "my-openaccounting-attachments",
+      "prefix": "attachments",
+      "access_key_id": "AKIA...",
+      "secret_access_key": "...",
+      "endpoint": "",
+      "path_style": false
+    }
+  }
+}
+```
+
+**Environment Variables:**
+```bash
+OA_STORAGE_BACKEND=s3
+OA_STORAGE_S3_REGION=us-east-1
+OA_STORAGE_S3_BUCKET=my-openaccounting-attachments
+OA_STORAGE_S3_PREFIX=attachments
+OA_STORAGE_S3_ACCESS_KEY_ID=AKIA...
+OA_STORAGE_S3_SECRET_ACCESS_KEY=...
+```
+
+**Features:**
+- Automatic presigned URL generation
+- Configurable expiry times
+- Support for S3-compatible services (MinIO, DigitalOcean Spaces)
+- IAM role support (leave credentials empty to use IAM)
+
+### 3. Backblaze B2 Storage
+Cost-effective cloud storage alternative to S3.
+
+**Configuration:**
+```json
+{
+  "storage": {
+    "backend": "b2",
+    "b2": {
+      "account_id": "your-b2-account-id",
+      "application_key": "your-b2-application-key",
+      "bucket": "my-openaccounting-attachments", 
+      "prefix": "attachments"
+    }
+  }
+}
+```
+
+**Environment Variables:**
+```bash
+OA_STORAGE_BACKEND=b2
+OA_STORAGE_B2_ACCOUNT_ID=your-b2-account-id
+OA_STORAGE_B2_APPLICATION_KEY=your-b2-application-key
+OA_STORAGE_B2_BUCKET=my-openaccounting-attachments
+OA_STORAGE_B2_PREFIX=attachments
+```
+
+## API Endpoints
+
+The storage system provides both legacy and new endpoints:
+
+### New Storage-Agnostic Endpoints
+
+**Upload Attachment:**
+```
+POST /api/v1/attachments
+Content-Type: multipart/form-data
+
+transactionId: uuid
+description: string (optional)
+file: binary data
+```
+
+**Get Attachment Metadata:**
+```
+GET /api/v1/attachments/{id}
+```
+
+**Get Download URL:**
+```
+GET /api/v1/attachments/{id}/url
+```
+
+**Download File:**
+```
+GET /api/v1/attachments/{id}?download=true
+```
+
+**Delete Attachment:**
+```
+DELETE /api/v1/attachments/{id}
+```
+
+### Legacy Endpoints (Still Supported)
+The original transaction-scoped endpoints remain available for backward compatibility:
+- `GET/POST /api/v1/orgs/{orgId}/transactions/{transactionId}/attachments`
+
+## Security Features
+
+- **File type validation** - Only allowed MIME types are accepted
+- **File size limits** - Configurable maximum file size (default 10MB)
+- **Path traversal protection** - Prevents directory traversal attacks
+- **Access control** - Files are linked to users and organizations
+- **Presigned URLs** - Time-limited access for cloud storage
+
+## File Organization

+Files are automatically organized by date:
+```
+uploads/
+├── 2025/
+│   ├── 01/
+│   │   ├── 15/
+│   │   │   ├── uuid1.pdf
+│   │   │   └── uuid2.png
+│   │   └── 16/
+│   │       └── uuid3.jpg
+```
+
+## Configuration Examples
+
+### Development (Local Storage)
+```json
+{
+  "storage": {
+    "backend": "local",
+    "local": {
+      "root_dir": "./dev-uploads"
+    }
+  }
+}
+```
+
+### Production (S3 with IAM)
+```json
+{
+  "storage": {
+    "backend": "s3", 
+    "s3": {
+      "region": "us-west-2",
+      "bucket": "prod-openaccounting-files",
+      "prefix": "attachments"
+    }
+  }
+}
+```
+
+### Cost-Optimized (Backblaze B2)
+```json
+{
+  "storage": {
+    "backend": "b2",
+    "b2": {
+      "account_id": "${B2_ACCOUNT_ID}",
+      "application_key": "${B2_APP_KEY}",
+      "bucket": "openaccounting-prod"
+    }
+  }
+}
+```
+
+## Migration Between Storage Backends
+
+When changing storage backends, existing attachments will remain in the old storage location. The database records contain the storage path, so files can be accessed until migrated.
+
+To migrate:
+1. Update configuration to new backend
+2. Restart server
+3. New uploads will use the new backend
+4. Optional: Run migration script to move existing files
+
+## Environment-Specific Considerations
+
+### Self-Hosted
+- Use local storage for simplicity
+- Ensure backup strategy includes upload directory
+- Consider disk space management
+
+### Cloud Deployment  
+- Use S3 or B2 for reliability and scalability
+- Configure proper IAM policies
+- Enable versioning and lifecycle policies
+
+### Multi-Region
+- Use cloud storage with appropriate region selection
+- Consider CDN integration for better performance
+
+## Troubleshooting
+
+**Storage backend not initialized:**
+- Check configuration syntax
+- Verify credentials for cloud backends
+- Ensure storage directories/buckets exist
+
+**Permission denied:**
+- Check file system permissions for local storage
+- Verify IAM policies for S3
+- Confirm B2 application key permissions
+
+**Large file uploads failing:**
+- Check `MaxFileSize` configuration
+- Verify network timeouts
+- Consider multipart upload for large files

-# SemVer
-
-The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
-
-* Parse semantic versions
-* Sort semantic versions
-* Check if a semantic version fits within a set of constraints
-* Optionally work with a `v` prefix

-If you are looking for a command line tool for version comparisons please see
-[vert](https://github.com/Masterminds/vert) which uses this library.
-
-## Parsing Semantic Versions
-
-To parse a semantic version use the `NewVersion` function. For example,
-
-```go
-    v, err := semver.NewVersion("1.2.3-beta.1+build345")
-```
-
-If there is an error the version wasn't parseable. The version object has methods
-to get the parts of the version, compare it to other versions, convert the
-version back into a string, and get the original string. For more details
-please see the [documentation](https://godoc.org/github.com/Masterminds/semver).
-
-## Sorting Semantic Versions
-
-A set of versions can be sorted using the [`sort`](https://golang.org/pkg/sort/)
-package from the standard library. For example,
-
-```go
-    raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
-    vs := make([]*semver.Version, len(raw))
-	for i, r := range raw {
-		v, err := semver.NewVersion(r)
-		if err != nil {
-			t.Errorf("Error parsing version: %s", err)
-		}
-
-		vs[i] = v
-	}
-
-	sort.Sort(semver.Collection(vs))
-```
-
-## Checking Version Constraints
-
-Checking a version against version constraints is one of the most featureful
-parts of the package.
-
-```go
-    c, err := semver.NewConstraint(">= 1.2.3")
-    if err != nil {
-        // Handle constraint not being parseable.
-    }
-
-    v, _ := semver.NewVersion("1.3")
-    if err != nil {
-        // Handle version not being parseable.
-    }
-    // Check if the version meets the constraints. The a variable will be true.
-    a := c.Check(v)
-```
-
-## Basic Comparisons
-
-There are two elements to the comparisons. First, a comparison string is a list
-of comma separated and comparisons. These are then separated by || separated or
-comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
-comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
-greater than or equal to 4.2.3.
-
-The basic comparisons are:
-
-* `=`: equal (aliased to no operator)
-* `!=`: not equal
-* `>`: greater than
-* `<`: less than
-* `>=`: greater than or equal to
-* `<=`: less than or equal to
-
-## Working With Pre-release Versions
-
-Pre-releases, for those not familiar with them, are used for software releases
-prior to stable or generally available releases. Examples of pre-releases include
-development, alpha, beta, and release candidate releases. A pre-release may be
-a version such as `1.2.3-beta.1` while the stable release would be `1.2.3`. In the
-order of precidence, pre-releases come before their associated releases. In this
-example `1.2.3-beta.1 < 1.2.3`.
-
-According to the Semantic Version specification pre-releases may not be
-API compliant with their release counterpart. It says,
-
-> A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version.
-
-SemVer comparisons without a pre-release comparator will skip pre-release versions.
-For example, `>=1.2.3` will skip pre-releases when looking at a list of releases
-while `>=1.2.3-0` will evaluate and find pre-releases.
-
-The reason for the `0` as a pre-release version in the example comparison is
-because pre-releases can only contain ASCII alphanumerics and hyphens (along with
-`.` separators), per the spec. Sorting happens in ASCII sort order, again per the spec. The lowest character is a `0` in ASCII sort order (see an [ASCII Table](http://www.asciitable.com/))
-
-Understanding ASCII sort ordering is important because A-Z comes before a-z. That
-means `>=1.2.3-BETA` will return `1.2.3-alpha`. What you might expect from case
-sensitivity doesn't apply here. This is due to ASCII sort ordering which is what
-the spec specifies.
-
-## Hyphen Range Comparisons
-
-There are multiple methods to handle ranges and the first is hyphens ranges.
-These look like:
-
-* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
-* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
-
-## Wildcards In Comparisons
-
-The `x`, `X`, and `*` characters can be used as a wildcard character. This works
-for all comparison operators. When used on the `=` operator it falls
-back to the pack level comparison (see tilde below). For example,
-
-* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-* `>= 1.2.x` is equivalent to `>= 1.2.0`
-* `<= 2.x` is equivalent to `< 3`
-* `*` is equivalent to `>= 0.0.0`
-
-## Tilde Range Comparisons (Patch)
-
-The tilde (`~`) comparison operator is for patch level ranges when a minor
-version is specified and major level changes when the minor number is missing.
-For example,
-
-* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
-* `~1` is equivalent to `>= 1, < 2`
-* `~2.3` is equivalent to `>= 2.3, < 2.4`
-* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-* `~1.x` is equivalent to `>= 1, < 2`
-
-## Caret Range Comparisons (Major)
-
-The caret (`^`) comparison operator is for major level changes. This is useful
-when comparisons of API versions as a major change is API breaking. For example,
-
-* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
-* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
-* `^2.3` is equivalent to `>= 2.3, < 3`
-* `^2.x` is equivalent to `>= 2.0.0, < 3`
-
-# Validation
-
-In addition to testing a version against a constraint, a version can be validated
-against a constraint. When validation fails a slice of errors containing why a
-version didn't meet the constraint is returned. For example,
-
-```go
-    c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
-    if err != nil {
-        // Handle constraint not being parseable.
-    }
-
-    v, _ := semver.NewVersion("1.3")
-    if err != nil {
-        // Handle version not being parseable.
-    }
-
-    // Validate a version against a constraint.
-    a, msgs := c.Validate(v)
-    // a is false
-    for _, m := range msgs {
-        fmt.Println(m)
-
-        // Loops over the errors which would read
-        // "1.3 is greater than 1.2.3"
-        // "1.3 is less than 1.4"
-    }
-```

-Package semver provides the ability to work with Semantic Versions (http://semver.org) in Go.
-
-Specifically it provides the ability to:
-
-    * Parse semantic versions
-    * Sort semantic versions
-    * Check if a semantic version fits within a set of constraints
-    * Optionally work with a `v` prefix
-
-Parsing Semantic Versions
-
-To parse a semantic version use the `NewVersion` function. For example,
-
-    v, err := semver.NewVersion("1.2.3-beta.1+build345")
-
-If there is an error the version wasn't parseable. The version object has methods
-to get the parts of the version, compare it to other versions, convert the
-version back into a string, and get the original string. For more details
-please see the documentation at https://godoc.org/github.com/Masterminds/semver.
-
-Sorting Semantic Versions
-
-A set of versions can be sorted using the `sort` package from the standard library.
-For example,
-
-    raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
-    vs := make([]*semver.Version, len(raw))
-	for i, r := range raw {

-
-Checking Version Constraints
-
-Checking a version against version constraints is one of the most featureful
-parts of the package.
-
-    c, err := semver.NewConstraint(">= 1.2.3")
-    if err != nil {
-        // Handle constraint not being parseable.
-    }
-
-    v, err := semver.NewVersion("1.3")
-    if err != nil {
-        // Handle version not being parseable.
-    }
-    // Check if the version meets the constraints. The a variable will be true.
-    a := c.Check(v)
-
-Basic Comparisons
-
-There are two elements to the comparisons. First, a comparison string is a list
-of comma separated and comparisons. These are then separated by || separated or
-comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
-comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
-greater than or equal to 4.2.3.
-
-The basic comparisons are:
-
-    * `=`: equal (aliased to no operator)
-    * `!=`: not equal
-    * `>`: greater than
-    * `<`: less than
-    * `>=`: greater than or equal to
-    * `<=`: less than or equal to
-
-Hyphen Range Comparisons
-
-There are multiple methods to handle ranges and the first is hyphens ranges.
-These look like:
-
-    * `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
-    * `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
-
-Wildcards In Comparisons
-
-The `x`, `X`, and `*` characters can be used as a wildcard character. This works
-for all comparison operators. When used on the `=` operator it falls
-back to the pack level comparison (see tilde below). For example,
-
-    * `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-    * `>= 1.2.x` is equivalent to `>= 1.2.0`
-    * `<= 2.x` is equivalent to `<= 3`
-    * `*` is equivalent to `>= 0.0.0`
-
-Tilde Range Comparisons (Patch)
-
-The tilde (`~`) comparison operator is for patch level ranges when a minor
-version is specified and major level changes when the minor number is missing.
-For example,
-
-    * `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
-    * `~1` is equivalent to `>= 1, < 2`
-    * `~2.3` is equivalent to `>= 2.3, < 2.4`
-    * `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
-    * `~1.x` is equivalent to `>= 1, < 2`
-
-Caret Range Comparisons (Major)
-
-The caret (`^`) comparison operator is for major level changes. This is useful
-when comparisons of API versions as a major change is API breaking. For example,
-
-    * `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
-    * `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
-    * `^2.3` is equivalent to `>= 2.3, < 3`
-    * `^2.x` is equivalent to `>= 2.0.0, < 3`
