Install a ready-made form on this number

/api/channels/:channel/whatsapp/flows

Creates the form on the Business Account and PUBLISHES it in the same call. Published immediately because a draft cannot be sent to anyone: an operator who pressed install and got something unusable would reasonably read that as a failure.

Installed and published.

403

Authenticated but not allowed.

404

Resource not found (or not visible to the current tenant).

409

Meta refused the form. details carries Meta's own validation sentence, which names the component it choked on.
