refactor: update data access layer to use GORM repositories

- Replace SQL-based queries with GORM repository calls
- Update all model interfaces to use repository pattern
- Fix compilation errors in core/model/ files
- Update mocks to match new repository interfaces
- Modify API handlers to use new repository layer
- Maintain backward compatibility with existing interfaces
