When a contact sends an image or other attachment, the webhook payload does not provide a direct URL to that file. This makes it difficult for external systems (CRMs, ticketing tools, custom AI/services) to fetch and process the latest attachment without additional API calls or manual steps.

Add the ability for webhooks (e.g., New Incoming Message) to include the public or time-limited signed URL(s) of attachments from the message, along with basic metadata (file type, size, filename, channel, timestamp).
