Subject: [PATCH] fix: namespace label cache key on discography pages to
 prevent artist MBID collision

On discography/band pages, the label lookup used the bare URL as
the cache key (e.g. 'https://example.bandcamp.com'). This is the
same key the artist lookup uses. When a label was found, its MBID
was cached under the bare URL. On subsequent album page visits,
resolveMBID(root_url) would find that label MBID and incorrectly
seed it as the release artist credit, causing MusicBrainz to reject
the import with 'Invalid artist_credit.names.0.mbid'.

The fix adds a 'label:' prefix to the cache key, matching the
pattern already used on album pages (line 610).
