Adds sort_name/cover_url to ArtistRef, sort_title to AlbumRef (matching
backend Task 5 wire shape), HomePayload type, and qk.home/albumsAlpha/
artistTracks query keys. Updates existing test fixtures to satisfy the
new required fields.
Verified clean via 'npm run check' (0 errors, only pre-existing warnings).

Each section is its own infinite query against /api/likes/{type}.
Empty sections show 'No liked X yet' (gated on total === 0). Reuses
ArtistRow / AlbumCard / TrackRow for rendering — same components as
the search overflow pages.
