fix(composers): hide performer-only artists with zero composer credits (#963)

* fix(composers): drop Navidrome role rows with zero composer albums

Navidrome can list performer-only artists under role=composer with
stats.composer.albumCount 0; filter them out of the Composers catalog
so search no longer surfaces ghost entries like Apollo 440.

* docs(changelog): credit zunoz on Psysonic Discord for PR #963

 * Multi-select rings on Artists, All Albums, Playlists, and related card grids use an inset `::after` overlay (same approach as card focus rings) instead of `outline` on `overflow: hidden` tiles — fixes top-row clipping and the ~1px gap vs the inner border on Wayland/WebKitGTK.

+* Navidrome's composer role list can include artists with zero composer album credits (e.g. Apollo 440 with performer albums only). Composers browse/search now drops rows where `stats.composer.albumCount` is zero so ghost composer cards no longer appear.
