merge: Phase 1 image system implementation complete
- Database: Added photo_path, photo_thumbnail_path, photo_upload_date fields
- Services: ImageStorage (file ops) + ImageProcessor (image processing pipeline)
- API: POST/PUT /api/items/{id}/photo upload endpoints with validation
- API: GET /api/items/{id} returns photo URLs
- Static: FastAPI StaticFiles mount for /images/ directory
- Tests: 127+ comprehensive tests across all components
- Security: Fixed race conditions, path traversal, crop validation
- Ready for Phase 2 (frontend UI)
