Submit a decision for a session paused at an external gate step. The session must be in `awaiting_external` status. **Decisions:** - `continue` — resume executing the remaining workflow steps. - `fail` — apply the gate step's `on_fail` action (e.g. review, reject, or jump to another step). - `reject` — immediately reject the session. The workflow resumes asynchronously after the decision is accepted.
