Posts an order completed on a connected POS provider's terminal, such as Clover, to a reservation's or group's folio, with its items, taxes, discounts and service charges. The terminal's merchant must be connected to the property; otherwise 403 (integration_disconnected).

Idempotency-Key is required: retrying with the same key returns the original result, and reusing a key with a different payload returns 409. A failed post writes nothing to the folio. To correct a charge, void it and charge again with a new key.

Errors return detail as {code, message, retryable}.
