fix(tickets): refresh status and resources in detail panel after update

Status update was returning only new_status (string) and the parent list's
onStatusUpdated only set status_name. The <select> was bound to status_id,
which never changed — so it visually reverted to the old status even though
the PATCH succeeded.

- Backend: include new_status_id in the status-update response.
- Panel: own currentStatusId/currentStatusName state so the select reflects
  the change immediately and survives stale parent snapshots.
- Parent list: update status_id on both the row and selectedTicket so the
  list row stays in sync when the panel stays open.
