Approve, reject, request-changes, expiry and escalation staged their work
order audit with WorkOrderId = dispatch.WorkOrderId ?? 0. WorkOrderAuditLogs
requires a real work order, so any uplift on a dispatch without an owning
work order failed to save: the decision returned a 500 and the request stayed
Pending, and the expiry sweep failed on it every run.
The audit now goes to the work order the uplift resolves to through the
existing owner-or-linked read that revoke already uses. When none resolves,
the status change is saved on the request and no audit row is written.
