Security Enhancement:
- Server-side validation of email status before allowing unsubscribe
- Only allow unsubscribing from verified emails
- Show "Action Not Allowed" message for unverified/unsubscribed emails
- Extract and validate share-id on server side
- Return 404 for invalid share-ids or missing tenant emails
Implementation:
- Convert page.tsx to async server component
- Fetch location and check tenantEmailStatus
- Pass isVerified prop to client component
- Add bilingual "not-allowed" translations
