Draft an outbound calling campaign (campaigns scope required). Never places calls.

Creates a DISABLED campaign draft that a human team manager must review and launch in the Canarics dashboard (Outbound tab); no calls are placed by this endpoint. The brief becomes the calling agent's only context, so ground it in what the company actually wants from these calls. Audience is either an existing lead pool (poolId) or up to 200 numbers the company already has a lawful basis to call. Once launched by the manager, calls run through the normal outbound loop: daily limit, local calling window, retries, spacing.
