 * Maps a rejected login reported by an extension's `refreshToken` in a common error shape onto

 * error or its `cause` chain: an OAuth error code that the built-in providers treat as a rejected login (such as
 * `invalid_grant`), in the error's `error` or `code` property or in an OAuth error response (flat or nested
 * `error.code`) in `body`, `data`, `response.data`, or `response.body`; or HTTP 401 in `status`, `statusCode`,
 * `response.status`, or `response.statusCode`. Errors that already are an `OAuthRefreshRejectedError` are left as
 * thrown.
