refactor(artist-detail): G.84 — extract helpers + suggestion cover + 2 data hooks + play utilities (cluster) (#651)

Five-cut cluster opening the ArtistDetail refactor. 944 → 631 LOC
(−313).

artistDetailHelpers — formatDuration (M:SS) + sanitizeHtml (strip
script/style/iframe/etc tags + onXxx + javascript: / data: hrefs).

ArtistSuggestionTrackCover — tiny CachedImage wrapper for the
32×32 cover thumbnail in the suggestions tracklist.

useArtistDetailData — owns the page's three primary fetch effects:
getArtist + getTopSongs on artist id change, getArtistInfo on id +
audiomuseNavidromeEnabled change, and the background "Also Featured
On" search that derives albums from search results not in the
artist's own album set. Exposes artist / setArtist / albums /
topSongs / info / featuredAlbums / loading flags + isStarred for
the star button.

useArtistSimilarArtists — owns the two parallel similar-artist
effects (Last.fm primary path when AudioMuse is off; Last.fm
fallback when AudioMuse is on but returned nothing) plus the
audiomuse-positive-result reset. Returns { similarArtists,
similarLoading }.

runArtistDetailPlay — three play orchestrators that share the
fetchAllTracks helper: runArtistDetailPlayAll, runArtistDetailShuffle,
runArtistDetailStartRadio (with the no-radio fallback alert). All
take deps objects so the page just delegates state setters.

ArtistDetail drops the now-unused direct search / getArtistInfo /
getTopSongs / getSimilarSongs2 / getArtist / lastfmGetSimilarArtists
imports. Pure code move otherwise.
