Consolidates storage backends into a single S3-compatible driver that supports:
- AWS S3 (native)
- Backblaze B2 (S3-compatible API)
- Cloudflare R2 (S3-compatible API)
- MinIO and other S3-compatible services
- Local filesystem for development
This replaces the previous separate B2 driver with a unified approach,
reducing dependencies and complexity while adding support for more services.
