Add GIF-to-MP4 playback support (v1.5.2)

Features:
- Detect GIF URLs automatically
- Request conversion from alfred-proxy /api/convert-gif endpoint
- Display loading indicator during conversion
- Play MP4 in looping VideoView component
- Auto-start playback on load
- Error handling with user-friendly messages

Technical details:
- Uses AndroidView wrapper for VideoView in Compose
- Coroutines for async conversion request
- Gateway URL from SharedPreferences
- Falls back to static image for non-GIF images

Tested successfully with Tenor GIFs - smooth playback confirmed!
