Release a transaction's reservations (phase two — abort by transaction)
Use this endpoint to release every reservation a transaction holds in a single call, addressing them by the ledger transactionId — phase two of the two-phase reservation flow. The response reports how many reservations were transitioned in flipped. A flipped value of 0 is a valid, idempotent success — the transaction held no open reservations.
