Resolve quarantined return units (restock or writeoff)
Resolves units a return disposition placed on HOLD in inventory (quarantine_qty). Per item, resolution=restock moves the held quantity back to on-hand (GL-neutral) and resolution=writeoff drops it to zero and posts a GL writeoff (DR inventory shrink / CR inventory FG). All writeoff JEs from one call group under a single batch id.
A mis-shipment RMA that is still in the expected staging state cannot be resolved here (422 misship_expected_not_resolvable): the wrong unit has not been received yet, so it must flow through the normal receive then disposition path first.
Authorization: requires returns:write scope plus the returns.process SoD permission. Idempotent via the Idempotency-Key header and a per-item held-quantity cap.
