fix: “Continue watching” does not display titles with the updated language

[Aaronnn17]

I'm reopening the pull request because I was creating the previous one from my “main” branch and didn't realize it. I'm reopening this one from another appropriate branch.

I think I've fixed the issues you mentioned earlier, and I've tested it in Android Studio to make sure it doesn't crash during compilation.

Please forgive me for any other errors—I'm a total beginner at programming, and these are the first mini-projects I've ever done!

Thanks for reopening this and addressing the earlier feedback. The PR now compiles, covers both Trakt and fallback items, and limits processing to 50 rows, so it is much closer.

I found two remaining issues before merge:

1. Launcher refresh is still too expensive. The final selectedItems.map calls full getMovieDetails() / getTvDetails() for every item and getSeasonEpisodes() for every TV episode, sequentially. These methods also do unrelated IMDb-rating and watched-state work. Because launcher refresh is called from several playback/history actions, this can generate many requests and make launcher updates slow. Please use lightweight TMDB calls that fetch only the localized title/episode title, with bounded concurrency and a small language-aware cache.

2. A language change may still keep the old title. MediaRepository caches details using only the media ID, not the language, and changing contentLanguage does not invalidate those caches. setContentLanguage() also does not refresh the launcher rows. Please make these title caches language-aware (or clear them when language changes) and call launcherContinueWatchingRepository.refreshForCurrentProfile() after changing the language.

Minor cleanup: git diff --check reports trailing whitespace on lines 103 and 173.

The exact merge into current main is clean, GitHub Build Check passes, and both Play/Sideload compiles and unit-test suites pass. The idea is useful; fixing the two points above should make it reliable and safe to merge.
