* feat(genre): add paginated songs-by-genre API
Wraps the Subsonic getSongsByGenre endpoint plus a fetchAllSongsByGenre
helper that paginates until exhausted, capped to keep the queue and the
burst of requests bounded for very large genres.
* refactor(playback): extract shared bulk play/shuffle/enqueue helper
A single fetchTracks-driven core (loading flag, empty guard, canonical
shuffleArray) so async detail-page play buttons stop growing divergent
copies. Artist detail now reuses it, dropping its weaker sort-random
shuffle.
* feat(genre): play, shuffle and queue buttons on the genre view
Header buttons load the genre's songs and start ordered or shuffled
playback, or append them to the queue. The slice is bounded to stay
within the queue resolver's cache budget so every row resolves instead
of rendering as a placeholder. Strings added across all nine locales.
* docs(changelog): genre play/shuffle buttons (#926)
