Subject: [PATCH] Fix camera upload errors on Android and improve mobile
performance

## Recent Changes
### October 14, 2025
+- **Android Camera Upload Fix**: Fixed critical Android camera capture bug where uploads failed with 400 error. Android devices send captured files with invalid names (empty, 'blob', etc.) that Multer rejects. Solution: `handleCameraCapture` now detects invalid filenames and creates new File object with generated name `camera-${timestamp}.${extension}` while preserving MIME type. Applied to both new-post and media-upload components. iPhone functionality unaffected.
- **Mobile Performance Optimizations**: Implemented comprehensive mobile speed optimizations for "Nouvelle publication" and "Médiathèque" pages. Changes include: (1) Adaptive initial loading - 6 media items on mobile (<768px), 12 on desktop; (2) Optimized thumbnail URLs - replaced `originalUrl` with `facebookFeedUrl` (1080x1080 Cloudinary transformed images) for 70-90% reduction in data transfer while keeping `originalUrl` for zoom/preview quality; (3) Native lazy loading - added `loading="lazy"` attribute to all `![]()
` tags for deferred off-screen image loading; (4) Responsive grid layout - 2 columns on mobile, 3 on desktop (sm:grid-cols-3) for better touch targets. Expected impact: Initial load time reduced from 3-5s to <1s on mobile devices.
- **Camera Capture in Media Library**: Added camera button 📷 to MediaUpload component, mirroring functionality from new-post page. Mobile users (lg:hidden) can now capture photos/videos directly from device camera and auto-upload to media library. Implementation includes hidden file input with `capture="environment"`, `handleCameraCapture` handler with input value reset (`e.target.value = ''`) to enable repeated captures, and integration with existing `uploadMutation` for seamless cloud storage.
- **Video Publishing for Facebook**: Implemented complete video support for Facebook feed and stories. Added `publishVideoPost()` method using `/videos` endpoint with `file_url` parameter for feed videos, and `publishVideoStory()` using `/video_stories` endpoint for story videos. Modified `publishStory()` to detect video media type and route to appropriate handler. Updated `publishPost()` logic to separate image vs video media filtering and use correct publishing methods. Video preview now uses `
