Show bitrate in browser, remove type labels and Play All text

- Extract bitrate alongside duration in browse_directory via get_media_info
- Display bitrate in large card view metadata (duration · bitrate · size)
- Replace Audio/Video type badge with bitrate column in list view
- Remove Play All button text, keep icon only
- Add formatBitrate helper function
