Genrekort: bara Utforska + YT; popupen visar kortrutnät med artister och låtar

Utforska-popupen renderar två MusicCard-grids (bilder, Hämta, ▶ YT) —
genrens låtar berikas nu också med artist-mbid/omslag i backend
(cachade uppslag så samma artist inte slås upp dubbelt). Äldre
batcher normaliseras i modalen.
