Reject an agent action

Reject a pending agent action, preventing execution. The action must have status PENDING_APPROVAL. Once rejected, the action transitions to REJECTED and the underlying operation is not executed. This endpoint is called by the platform’s backend using platform credentials, not by the agent itself.
