feat: dynamic video extractor, subtitle encoding fix, adaptive bitrate, seek mode

- Rewrite VideoExtractor for dynamic redirect following (no hardcoded domains)
- Parse player CONFIG JSON and call stream API directly (vaplayer.ru)
- Fallback to HTML scraping for old-style pages (cloudnestra)
- Fix subtitle encoding: detect ISO-8859-1, save as UTF-8 for proper ñ/accents
- Show up to 10 Spanish subtitle sources from OpenSubtitles
- Subtitle picker auto-scrolls to selected option
- State-based D-pad navigation for all controls and subtitle picker
- Seek mode: DPAD_UP enters, LEFT/RIGHT seeks, CENTER/DOWN applies
- Adaptive bitrate: ExoPlayer auto-selects quality based on bandwidth
- Reduce buffer sizes for Chromecast (15s/30s instead of 100s)
- Fix availableSubtitles stale capture in DisposableEffect key
