feat: add RgShows and IframeVideo streaming players

🎬 New Streaming Players Added:
- RgShows player for movies and TV shows via TMDB ID
- IframeVideo player using Kinopoisk ID and IMDB ID
- Unified players manager for multiple streaming providers
- JSON API endpoints for programmatic access

📡 RgShows Player Features:
- Direct movie streaming: /api/v1/players/rgshows/{tmdb_id}
- TV show episodes: /api/v1/players/rgshows/{tmdb_id}/{season}/{episode}
- HTTP API integration with rgshows.com
- 40-second timeout for reliability
- Proper error handling and logging

🎯 IframeVideo Player Features:
- Two-step authentication process (search + token extraction)
- Support for both Kinopoisk and IMDB IDs
- HTML iframe parsing for token extraction
- Multipart form data for video URL requests
- Endpoint: /api/v1/players/iframevideo/{kinopoisk_id}/{imdb_id}

🔧 Technical Implementation:
- Clean Go architecture with pkg/players package
- StreamResult interface for consistent responses
- Proper HTTP headers mimicking browser requests
- Comprehensive error handling and logging
- RESTful API design following existing patterns

🌐 New API Endpoints:
- /api/v1/players/rgshows/{tmdb_id} - RgShows movie player
- /api/v1/players/rgshows/{tmdb_id}/{season}/{episode} - RgShows TV player
- /api/v1/players/iframevideo/{kinopoisk_id}/{imdb_id} - IframeVideo player
- /api/v1/stream/{provider}/{tmdb_id} - JSON API for stream info

✅ Quality Assurance:
- All code passes go vet without issues
- Proper Go formatting applied
- Modular design for easy extension
- No breaking changes to existing functionality

Ready for production deployment! 🚀
