fix(player): retain subtitle language and mode across episodes

Carry the live subtitle/audio selection to the next episode on all TV
navigation paths (next/prev buttons, autoplay) and feed TV subtitle modal
selections back into player state via onSubtitleIndexChange so the chosen
track is what gets carried.

Rank subtitles by language plus forced/hearing-impaired mode, with a
no-language fallback (mode + codec + position), and use an explicit match
flag so a deliberate "off" selection is retained too.
