Use new ?unionid=X&status=2 login support on teacher.moicen.com instead of the complex cookie-injection workaround (login on music-room → extract JWT → inject into teacher domain via document.cookie). Also seed course packages to both orgs (慧正书法 + 慧添翼) so the test works regardless of which org the role chooser selects first. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
