Cancel a pending Payment Intent.

Cancel a pending Payment Intent. Idempotent; 400 if already paid or refunded. Requires a Blackbird identity: link your agent wallet once at /connect, then call with x402 + SIWX (first call pays, later SIWX-signed calls are free); or pass a member JWT in the X-Blackbird-Token header.
