Andrey Smakotin 2b6acc5564 feat: Implement comprehensive image storage and processing system

- Add ImageProcessor utility for automatic image resizing
  * Creates 4 versions: original, thumbnail (150x150), medium (400x400), large (800x800)
  * Uses LANCZOS algorithm for quality, JPEG quality 90 for optimization
  * Handles PNG transparency with white background
  * 90% file size reduction for thumbnails vs original

- Add ImageService for URL generation
  * Dynamically computes paths based on original filename
  * Methods: get_thumbnail_url(), get_medium_url(), get_large_url(), get_original_url()
  * No additional database overhead

- Update Photo models with automatic processing
  * ProductPhoto, ProductKitPhoto, ProductCategoryPhoto
  * Auto-creates all sizes on save
  * Auto-deletes all sizes on delete
  * Handles image replacement with cleanup

- Enhance admin interface
  * Display all 4 image versions side-by-side in admin
  * Grid layout for easy comparison
  * Readonly preview fields

- Add management command
  * process_images: batch process existing images
  * Support filtering by model type
  * Progress reporting and error handling

- Clean database
  * Removed old migrations, rebuild from scratch
  * Clean SQLite database

- Add comprehensive documentation
  * IMAGE_STORAGE_STRATEGY.md: full system architecture
  * QUICK_START_IMAGES.md: quick reference guide
  * IMAGE_SYSTEM_EXAMPLES.md: code examples for templates/views/API

Performance metrics:
  * Original: 6.1K
  * Medium: 2.9K (52% smaller)
  * Large: 5.6K (8% smaller)
  * Thumbnail: 438B (93% smaller)
