feat: optimize mockup images with WebP and auto-regeneration

Browse Source

Convert mockup source images from JPG to WebP format for 76% size
reduction (20MB → 4.7MB). Variants are now auto-generated on startup
via Oban, keeping the same DRY approach as database images.

Changes:
- Add OptimizeWorker.enqueue_mockup/1 for filesystem images
- Extend VariantCache to check mockup sources on startup
- Update MockupGenerator to save source as optimized WebP
- Update .gitignore to ignore generated variants
- Convert 55 source mockups from JPG to WebP

The mockup pipeline now uses the same code paths as database images:
- Optimizer.to_optimized_webp/1 for source conversion
- Optimizer.process_file/3 for variant generation
- OptimizeWorker for Oban background processing
- VariantCache for startup cache validation
