feat(home): sort control for the Library Albums rail

Adds a compact dropdown in the Library Albums (favoriteAlbums) row header, left of the page chevrons: Recently added (default), First added (reverse), Random (shuffle). Reorders the cached base list in Rust with no re-fetch and re-fires artwork by the new index. Also corrects the stale HomeView comment that claimed the recently-played refresh lives in the toolbar (it is a row-header button). 8 locales updated.
