feat: full artist release list via artist/getReleasesList

Instead of relying on the limited preview in artist/page, fire a
separate artist/getReleasesList request per release type (album,
epSingle, live, compilation) in parallel when loading an artist.
Each result updates its section independently as it arrives, so the
page populates progressively without a single large request.

Also fixes the artist name in the status bar (was reading wrong field).
