Deny a parked emission
Terminalizes a PENDING_APPROVAL emission: a single distinct authorized actor denying flips it to FAILED with the reason recorded — one deny kills it (a denial is not subject to quorum). A FAILED emission is never claimed by the outbox dispatcher, so it never liquidates.

Headers
