fix: artist hero appears instantly; album names skip romaji conversion

Hero now only waits for getArtist (fast local Navidrome) before revealing.
getArtistImage (Last.fm lookup) was the 2-4s bottleneck when uncached —
it now resolves async and patches in the artist photo after the hero is
already visible.

Album card, album detail header, and home hero now display the raw album
name from Navidrome instead of converting to romaji when showRomaji is on.
