Implement complete image management system with file upload, listing, retrieval,
updates, alias assignment, and soft deletion.
**v1 API Routes:**
- `POST /api/v1/images/upload` - Upload single image file with database record
- `GET /api/v1/images` - List images with filters and pagination
- `GET /api/v1/images/:id` - Get single image by ID
- `PUT /api/v1/images/:id` - Update image metadata (alias, focal point, meta)
- `PUT /api/v1/images/:id/alias` - Assign project-scoped alias to image
- `DELETE /api/v1/images/:id` - Soft delete image
**Upload Endpoint Features:**
- Uses uploadSingleImage middleware for file handling
- Creates database record with image metadata
- Stores file in MinIO storage (uploads category)
- Supports optional alias and flowId parameters
- Returns ImageResponse with all metadata
**Route Features:**
- Authentication via validateApiKey middleware
- Project key requirement
- Rate limiting on upload endpoint
- Request validation with pagination
- Error handling with proper status codes
- Response transformation with toImageResponse converter
- Project ownership verification for all operations
**ImageService Integration:**
- Uses existing ImageService methods
- Supports filtering by flowId, source, alias
- Soft delete with deletedAt timestamp
- Alias validation and conflict detection
**Type Updates:**
- Updated ImageFilters with explicit | undefined for optional properties
- All response types already defined in responses.ts
**Technical Notes:**
- Upload creates both storage record and database entry atomically
- Focal point stored as JSON with x/y coordinates
- Meta field for flexible metadata storage
- File hash set to null (TODO: implement hashing)
- All Phase 4 code is fully type-safe with zero TypeScript errors

Implement complete flow management system with CRUD operations, computed counts,
and alias management capabilities for organizing generation chains.
**Core Service:**
- **FlowService**: Complete flow lifecycle management
- Create flows with initial empty aliases
- CRUD operations (create, read, update, delete)
- Computed counts for generations and images per flow
- Alias management (add, update, remove)
- Get flow's generations and images with pagination
- No soft delete (flows use hard delete)
**v1 API Routes:**
- `POST /api/v1/flows` - Create new flow
- `GET /api/v1/flows` - List flows with pagination and counts
- `GET /api/v1/flows/:id` - Get single flow with computed counts
- `GET /api/v1/flows/:id/generations` - List flow's generations
- `GET /api/v1/flows/:id/images` - List flow's images
- `PUT /api/v1/flows/:id/aliases` - Update flow aliases (add/modify)
- `DELETE /api/v1/flows/:id/aliases/:alias` - Remove specific alias
- `DELETE /api/v1/flows/:id` - Delete flow (hard delete)
**Route Features:**
- Authentication via validateApiKey middleware
- Project key requirement
- Request validation with pagination
- Error handling with proper status codes
- Response transformation with toFlowResponse converter
- Project ownership verification for all operations
**Type Updates:**
- Added ListFlowGenerationsResponse and ListFlowImagesResponse
- Updated GetFlowResponse to return FlowResponse (not FlowWithDetailsResponse)
- FlowService methods return FlowWithCounts where appropriate
**Technical Notes:**
- Flows don't have deletedAt column (no soft delete support)
- All count queries filter active generations/images only
- Alias updates are merged with existing aliases
- Empty flows return generationCount: 0, imageCount: 0
- All Phase 3 code is fully type-safe with zero TypeScript errors

Implement the complete image generation lifecycle with ImageService, GenerationService,
and v1 API endpoints. This enables end-to-end generation with alias support and flow management.
**Core Services:**
- **ImageService**: Full CRUD for images table
- Create/read/update/delete operations
- Soft delete support with deletedAt
- Project and flow alias assignment
- Storage key and file hash tracking
- Pagination and filtering
- **GenerationService**: Complete generation lifecycle orchestration
- Create generation records with pending status
- Resolve reference images via AliasService
- Call ImageGenService for AI generation
- Create image records in database
- Link images to generations
- Update generation status (processing → success/failed)
- Support for flow association and alias assignment
- Retry failed generations
- Soft/hard delete operations
**v1 API Routes:**
- `POST /api/v1/generations` - Create with references & aliases
- `GET /api/v1/generations` - List with filters & pagination
- `GET /api/v1/generations/:id` - Get with full relations
- `POST /api/v1/generations/:id/retry` - Retry failed generation
- `DELETE /api/v1/generations/:id` - Delete generation & output
**Route Features:**
- Authentication via validateApiKey middleware
- Project key requirement
- Rate limiting per API key
- Request validation with pagination
- Error handling with proper status codes
- Response transformation with type converters
**Type Updates:**
- Add explicit undefined to optional properties for exactOptionalPropertyTypes
- CreateGenerationParams interface for service layer
- GenerationFilters with proper optionals
**Infrastructure:**
- Mount v1Router at /api/v1 in app.ts
- Keep legacy routes for backward compatibility
- Versioned API structure for future iterations
**Technical Notes:**
- Reference image download temporarily skipped (TODO: storage key parsing)
- File hash computation temporarily disabled (TODO: helper method)
- File size set to 0 (TODO: get from storage)
- All Phase 2 code is fully type-safe with zero TypeScript errors
