- Added 'verified=true' parameter to backend redirect for hybrid approach
- Frontend now checks 'verified' parameter and shows error if not set
- Removed unused token logic from verify-success page (backend handles verification)
- Added warning UI for unverified emails with resend link
- Added Suspense boundary to verify-success/page.tsx
- Added Suspense boundary to verify-error/page.tsx
