Failing test: when postSelfServiceRegistrations errors, the page should show an alert, not the confirmation, and keep the submit button available for retry. Currently submit() has no error handler, so the rejection is swallowed and the page silently stays put — exactly the failure mode that hid the missing-token bug behind a 90s e2e timeout.
