The route contract keeps the poc endpoint from main and the uplift evidence routes from this branch. Create still passes the scanned evidence document through the locked mutation.
After SH-393 the uplift dispatch resolves only through dispatches the work
order owns or links through DispatchWorkOrders. Model the shared dispatch
that way so the concurrent-insert conflict test exercises the conflict
mapping again; assertions are unchanged.
