f12fd18190 refactor: Move image processing configuration to settings 
Refactored image processing system to use centralized configuration in settings.IMAGE_PROCESSING_CONFIG instead of hardcoded values.

Changes:
- Added IMAGE_PROCESSING_CONFIG to settings with configurable sizes, formats, and quality
- Rewrote ImageProcessor to use dynamic configuration from settings
- Added support for multiple image formats (JPEG, WebP, PNG)
- Updated _save_image_version() to handle different formats and quality levels
- Added original image scaling (max 2160×2160) and square aspect ratio
- Updated ImageService to work with different file extensions (.jpg, .webp, .png)
- All parameters now easily configurable without code changes

Configuration:
- Original: JPEG, quality 100, max 2160×2160 (always square)
- Large: WebP, quality 90, 1200×1200
- Medium: WebP, quality 85, 600×600
- Thumbnail: WebP, quality 80, 200×200

Benefits:
- Flexible and maintainable configuration
- Smaller file sizes (WebP for resized images)
- Maximum quality for originals (JPEG 100)
- Square aspect ratio for better consistency

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)
