Check channel and engine health
GEThttps://api.wapito.com/v1/channel/health
Send a channel token on every request: Authorization: Bearer wpt_YOUR_TOKEN
Pings the protocol engine behind the channel and reports how long the session has been up, when WhatsApp was last seen, how many sends and webhook deliveries are still queued, and the result of each individual probe. This is the endpoint to wire into an uptime monitor: it fails fast with `engine_unavailable` when the engine is down instead of hanging.
