Cancel a resting perp order on its venue (non-custodial). ``jurisdiction``: cancel is geo-gated too -- see place_perp_order. ``idempotency_key`` (optional): a client-generated UUID. Retrying with the same key + same args replays the original result instead of re-cancelling the order. Reuse the SAME key across the build call and its ``signed_transaction`` completion call -- see place_perp_order; the two legs dedupe independently, so this never raises IDEMPOTENCY_CONFLICT. ``signed_transaction`` / ``verify`` (two-phase execution): see place_perp_order. A cancel moves no position, so confirming the signature landed IS the verification -- no state re-read is declared.
