Audit v2 #12. Hidden rows were text-only ("title", "artist · album",
reason chip); Flutter shows the album cover thumbnail and a "3h ago"
relative-time stamp next to the reason. Both added to QuarantineRef
(coverUrl computed from albumId) and HiddenRow renders them.
Time helper is duplicated from HistoryTab inline rather than
hoisted — both copies are small and screen-private; a shared
RelativeTime widget can land later if a third caller surfaces.
