feat(web): order the In-queue tab next-up-first with a "Next up" marker

The queue tab showed newest-first (API returns createdAt desc) but the worker claims
the oldest queued job next (claim_next: ORDER BY createdAt ASC) — so the item that ran
next was at the BOTTOM. Sort the queue bucket ascending so it matches processing
order, and badge the first claimable row (oldest, not individually paused) as "Next up".
