Gigi 507288f51c feat: add image caching for offline mode
- Add imageCacheService with localStorage-based image caching and LRU eviction
- Create useImageCache hook for React components to fetch and cache images
- Integrate image caching with article service to cache cover images on load
- Add image cache settings (enable/disable, size limit) to user settings
- Update ReaderHeader to use cached images for article covers
- Update BookmarkViews (CardView, LargeView) to use cached images
- Add image cache configuration UI in OfflineModeSettings with:
  - Toggle to enable/disable image caching
  - Slider to set cache size limit (10-200 MB)
  - Display current cache stats (size and image count)
  - Clear cache button

Images are cached in localStorage for offline viewing, with a configurable
size limit (default 50MB). LRU eviction ensures cache stays within limits.
