Unavailable tracks (8): playlist rows now say when the WHOLE release is
gone (`releaseUnavailable`, one probe per distinct album of the pulled rows
through the library's helper); TrackRow's album link and "Go to album" go
dark on it instead of opening an empty page. Every row that opens an album
passes the names it knows (`openAlbumFrom`), so when the catalog answers
404 the page names the release: AlbumView renders an "unavailable" arm —
heading, "This release is no longer available on Qobuz." — with the
best-ranked alternatives Qobuz still sells (the replacement flow's ranking,
exposed as `ranked_alternatives`) in a rail; a network failure gets the
same page with "Couldn't load this release." and no rail.
Copy (9): the player bar's "+" and the track row menus (shared TrackRow
and the artist's Popular Tracks rows) gain a Copy entry with a submenu —
"Track name" or "Track - Album - Artist" — through the shared clipboard
carrier; CardMenu marks `submenu: true` entries with a chevron and the
host reopens the second menu on the same anchor. Row menus keep both lazy.
Buy on Qobuz (10): the album header shows a store action when the catalog
says the release is purchasable and it is not already owned; the track
menus and the player bar carry the same entry for catalog rows and resolve
it at click time — the store page opens in the browser, or a toast says
the release is not sold. The link is `https://www.qobuz.com/album/-/{id}`,
which the store answers with a 301 to the localised page (verified).
