This PR updates the video player logic to default to MSE (Media Source Extensions) for all browsers except Safari, replacing the previous Chrome-specific detection. This change ensures caption availability works consistently across Chromium-based browsers while maintaining native HLS playback for Safari.
Key changes:
- Replaced Chrome version detection with Safari user agent detection
- Inverted the logic to use MSE by default for non-Safari browsers
- Removed unused
