feat: Implement comprehensive torrent downloads management system

- Fix torrent platform service integration with Android engine
- Add downloads page with torrent list and progress tracking
- Implement torrent detail screen with file selection and priorities
- Create native video player with fullscreen controls
- Add WebView players for Vibix and Alloha
- Integrate corrected torrent engine with file selector
- Update dependencies for auto_route and video players

Features:
 Downloads screen with real-time torrent status
 File-level priority management and selection
 Three player options: native, Vibix WebView, Alloha WebView
 Torrent pause/resume/remove functionality
 Progress tracking and seeder/peer counts
 Video file detection and playback integration
 Fixed Android torrent engine method calls

This resolves torrent integration issues and provides complete
downloads management UI with video playback capabilities.
