WhatsApp automatic event detected

Fired when Meta's automatic event identification (opt-in during Embedded Signup; not available for EU/UK/JP businesses) detects a lead or purchase in a Click-to-WhatsApp conversation. Branch on eventName (LeadSubmitted | Purchase). Carries the ctwa_clid. Meta omits that clid on a minority of referrals on any number (coexistence or not, most often WhatsApp Status placements); when it does, this event can supply it and Zernio writes it back onto the conversation, so POST /v1/whatsapp/conversions becomes usable for the thread.
