QualityBadge has always owned a hover tooltip, but every AlbumCard host
passed only the tier, so the tip had nothing to say. The card gains a
qualityDetail input feeding the badge's label, and all fifteen mounts
now pass their model's detail (HomeCard rides its qualityLabel twin).
Un-hydrated Plex/remote rows surface their bare filetype — the known
honest fallback; an empty detail still shows no tooltip at all. The
Scene panel's own card already wired this and is untouched.
