+Register with just an email. The registration form no longer requires a phone
+number (it stays optional, validated only when provided), and a successful
+registration now routes to email verification (`/verifyEmailOTP`) instead of
+phone verification — matching the auth server's email-first registration. After
+verifying the email code the user is signed in.
