{# Detail-page mutation response (Keep/Pass/Untrack/handoff with context=detail).
   Swaps the action bar in place (primary target #detail-actions-<id>) AND
   refreshes the 관련 신호 section out-of-band, because this PR made that
   section's layout depend on item.status (Keep → unified timeline): a status
   flip that only re-rendered the action bar would leave the signals section
   stale — a kept item without its timeline, or an archived item still showing
   the Keep timeline — until a full reload (codex P2).

   Two data shapes: the action bar renders from the feed-card `item` (status /
   id / asset_id / successors); the signals section needs the full
   ItemDetailView (`signals_item`) for similar / timeline / alerts / history.
   `signals_item` is None only when the item vanished between the mutation and
   the reload — then there is nothing to refresh out-of-band. #}
