Cancel Upload

1. Ask the user for the session token or upload URL from the original upload response.
2. Call get_upload_status to confirm the upload is still in progress.
3. Confirm with the user that they want to cancel — this deletes the partial file and the stored session record.
4. Call cancel_upload with the session token or upload URL.
5. Confirm the upload was cancelled. Note that a 404 from Graph is treated as success (session already expired).
