Post Signup
POST
/auth/post-signup
Post-signup orchestration: create org + register Brevo contact.
Called once by the frontend after email verification succeeds. Idempotent: safe to call multiple times (org creation checks for existing org, Brevo contact uses update_enabled=True).
Returns: 200 with org info on success.
