/// Streams the binary for a WhatsApp attachment. This is the endpoint the `url` on a WhatsApp `attachments[]` entry points at, in both the `message.received` webhook and the List messages response.  **This is an authenticated endpoint, not a public link.** Send `Authorization: Bearer <your API key>` exactly as you would for any other call. Passing the URL straight to a browser, an LLM vision API, or a no-code \"download file\" step without the header returns `401`. This is the most common integration mistake on this endpoint, and it differs from Instagram, Facebook and Telegram, whose `attachments[].url` is a direct CDN link that needs no header.  **Fetch on receipt, not lazily.** WhatsApp media lives in Meta's media store, not ours, and it is removed after a limited retention window (currently 7 days, and Meta has been dropping some inbound media sooner). Once Meta drops it the media is unrecoverable and this endpoint answers `400` permanently, so retrying will never succeed. Download and store the bytes when the webhook arrives.
