`matching.reject`

Say a candidate bank transaction is not the payment for a receipt, using decisionId, expectedRevision, entryId, entryRevision, transactionId, an optional reason and idempotencyKey. That transaction is not suggested for the receipt again and the receipt goes to a person; the vendor pairing counts against future suggestions only when the line names a different vendor; matching reruns. Send undo: true to lift a rejection. Finance access required.
