Send human agent response
Sends a manual reply from a live agent. `sessionId` must be the contact's **current** session and that session must be in a human-handoff state (enable it first via the human-handoff endpoint). Targeting a stale, closed, or non-handoff session returns `400 {"error":{"message":"Human handoff is not enabled for this campaign","code":"BAD_REQUEST"}}` — despite the wording, the cause is the session, not a campaign-level setting.
