i18n: make two hardcoded titles translatable

Replace hardcoded English strings with t() and add the source keys:
- LibraryOptionsSheet 'Options' -> library.options.options_title
- MpvPlayerView.web iframe 'MPV Player' -> player.mpv_player_title
New keys only (English source); other locales fall back to English until translated via Crowdin, so no regression.
