Completes milestone #290. The sweeper has been running and the settings have been editable, but the list itself said nothing about either, so the only way to tell "not tried yet" from "asked twice and nothing came back" was to go and read the Requests queue. Each folder now carries its album's attempt record: how many times, when last, when next -- or that it gave up, with the reassurance that a file coming back and going missing later starts the process over. Null when nothing has been attempted, which is the common case for a folder that just went missing and would be noise on every row. next_attempt_at is computed, not stored. The schedule is a function of the attempt count and the current settings, so persisting it would go stale the moment an operator edited the backoff -- and the card lets them do exactly that. Needed a forward-looking formatter. relativeTime deliberately collapses a future timestamp to "just now" (pinned by its own test) because that is the right answer for a clock-skewed past event; it is the wrong one for a scheduled future attempt, which would have rendered "next just now". timeUntil is its companion rather than a sign-aware rewrite: the two read differently in the same sentence -- "last tried 3d ago, next in 4h" -- and a test asserts they disagree about the future on purpose, so nobody later "fixes" the divergence. The state lookup is one batched query for the whole page and best-effort: this is context on a list whose real job is showing what is missing, so a failure leaves the groups bare rather than failing the page. The settings service is read with a nil guard falling back to the shipped defaults, since contexts that wire routing without services exist and a backoff projection is not worth a nil-pointer panic (rule #48).
