Send WhatsApp test message
Sends a single template message directly via the META Cloud API,
**bypassing** the broadcast pipeline. No broadcast row is created,
**no SQS enqueue**, and **no credit is consumed**. Use this to verify
your template + variables before launching a real broadcast.
**Required scope:** `send_whatsapp`
**Rate limit:** 5 requests / 15 min / client
Your registered webhooks will still receive `delivered` / `failed` events
for the test message — only broadcast accounting and billing are skipped.
Authentication

Bearer API keys are issued from the in-app /api-management page. Each key has

IP whitelist.
