Download an attachment
Return an attachment's metadata and a short-lived URL to download its bytes. Searched across every organization your credential owns, so no selector is needed for a known id. Fetch downloadUrl directly with a GET; it expires after expiresInSeconds. Returns 404 if the attachment does not exist or belongs to an organization your credential cannot access.
