Consultar el estado de un mensaje

GET /v1/messages/:id

GET /v1/messages/:id con el msg_… que devolvió el POST (un id numérico → 404). Un único vocabulario de estado: queued | sending | sent | delivered | read | failed | held. ⚠ Terminales: solo read y failed. delivered NO es terminal (delivered→read es válido) — si cortás el polling en delivered no ves la lectura.

curl https://api.waiaconnect.com/v1/messages/msg_5d325780fe504d0f87eb45009d28ae4f \

# → { "id": "msg_…", "status": "delivered", "attempts": 1, "createdAt": "…Z", … }

  headers: { "Authorization": "Bearer wc_live_YOUR_API_KEY" }
});
const msg = await res.json();
console.log(msg.status); // queued|sending|sent|delivered|read|failed|held (terminal: read|failed)
