- Add prominent email verification success UI with resend button
- Show resend verification option when registration fails with "not verified" error
- Improve form spacing with space-y-4 for better visual consistency
- Add translations for resend verification in all languages (de, en, fr, it, es)
- Update all 13 app register pages to pass onResendVerification prop
