Create a HITL confirmation request. Sends an approval request to the channels configured on the referenced HITL config. First response wins.
Agent usage: The HITL config referenced by hitl_id must be authorized before you can create confirmations. If this returns a 403 or "not authorized" error, call request_hitl_authorization on the HITL config first, then wait for the user to approve via the messaging channel. After creating a confirmation, poll get_confirmation to check for approval/denial, or use get_confirmation_approval_link to generate a fresh link for the user.
Encryption is NOT optional: a HITL config cannot send confirmations without a keypair, the human approves by decrypting in their browser, and `message` must be a JSON ciphertext envelope. Plaintext is refused with 400 `message_not_encrypted`; an envelope sealed to another key with 400 `message_key_mismatch`. Choose the version by who must be able to decrypt:
- v1 (single-recipient): wraps the content key for the config owner only. Use ONLY when there are no enrolled non-owner approvers — with approvers enrolled it is refused with 400 `envelope_missing_approvers`.
- v2 (multi-recipient): additionally wraps the content key for each enrolled approver via an `approver_ek` map, so every approver can decrypt. Build it with the SDK `encryptMessageV2(plaintext, ownerPublicKey, hitlId, approverKeys)` after fetching the approvers via the SDK `getApproverKeys(hitlId)` (`GET /api/v1/hitl/:id/approver-keys`). AAD is the `hitlId`.
