Get a signed URL to upload a chat image

Issues a short-lived SAS URL to upload one image directly to storage, so multi-MB screenshots never transit this API. PUT the bytes to upload_url with headers x-ms-blob-type: BlockBlob and x-ms-blob-content-type: <mime>, then reference the returned blob_path in the attachments of POST /chat/sessions/<id>/messages. Allowed types: image/png, image/jpeg, image/gif, image/webp. Honour max_image_bytes — the API can’t see the bytes on this path. The blob path is server-chosen and scoped to this session.
