Replace the generic disc-icon row list (FavLabelRow) with FavLabelCard:
a 140px circular cover in an auto-fill grid, mirroring FavArtistCard and
the artists-grid layout. No-image labels show a disc-3 placeholder on an
indigo->violet gradient (1:1 with Tauri's label card). The grid renders
labels-visible and adds the "No labels match your search" state.
