obsidian-tc: Declined confirmations permit destructive calls

A vulnerability in obsidian-tc allowed destructive vault operations to execute even after a human explicitly declined confirmation, if a compliant but malfunctioning client or attacker-controlled client resubmitted with the same request state. The issue affected dispatch-gated tools on HTTP deployments with JWT authentication.
