feat(genres): local index genre browse with Subsonic fallback (#937)

* feat(genres): genre detail browse via local index with aligned counts

Move genre detail albums/play/shuffle onto the local library index with
Albums-style in-page scroll, session restore, and genre-scoped stash. Unify
genre album totals between the cloud and detail pages via
library_get_genre_album_counts, and fix grouped browse totals to count
distinct albums rather than matching tracks.

* perf(genres): local genre browse with scoped counts cache

Add dedicated Rust genre album pagination and indexes, slice-mode grid
loading, library-filter-aware counts, and a long-lived in-memory catalog
cache invalidated on sync so genre pages avoid repeated full-library SQL.

* fix(genres): restore scroll after album back; play hold-to-shuffle

Pin restore display count in refs so clearing the return stash no longer
reloads the genre grid mid-restore. Load the first SQL page only (60 rows),
use long-press on Play for shuffle, and add genre play tooltips.

* fix(genres): fall back to Subsonic byGenre when local index unavailable

Genre detail album grid now matches All Albums: try library_list_albums_by_genre
first, then getAlbumsByGenre when the index is off, not ready, or errors.

* docs: add CHANGELOG and credits for PR #937

### Genres — local index browse with Subsonic fallback
**By [@cucadmuh](https://github.com/cucadmuh), PR [#937](https://github.com/Psychotoxical/psysonic/pull/937)**
* **Genre detail** and the **Genres** cloud load album lists and counts from the local library index when it is ready; new SQLite indexes speed genre→album browse.
* When the index is disabled or not ready, the album grid falls back to Subsonic **byGenre** as before.
* Returning from an album restores genre-detail scroll; **Play** uses hold-to-shuffle like other browse pages.
* **Advanced Search** grouped album totals count distinct albums, not raw matching track rows.
