/**
* Send a free-consultation booking confirmation via WhatsApp.
*
* Mirrors whatsapp-board-invite.ts / whatsapp-otp.ts: routes through
* WhatsAppAdapter so non-prod safety guards (override number + dry-run in
* local/dev) apply. Falls back to console logging when WHATSAPP_ACCESS_TOKEN
* is unset so dev envs never fail on this flow.
*
* The template is expected to take 1 body param:
* {{1}} booking reference (e.g. CONS-A1B2C3D4)
*
* Best-effort by design — the caller (consultations.routes.ts) fires this
* without blocking the booking response, so a delivery failure here never
* fails the user-facing submission.
