feat: Premium zone sync improvements

1. Parallel Zone Downloads (CZDS): - Downloads up to 3 TLDs concurrently - Reduced sync time from 3+ min to ~1 min - Semaphore prevents ICANN rate limits 2. Email Alerts: - Automatic alerts when sync fails - Sends to admin email with error details - Includes success/error summary 3. Admin Zone Sync Dashboard: - New "Zone Sync" tab in admin panel - Shows all TLDs with domain counts - Manual "Sync Now" buttons for Switch/CZDS - Live stats: drops/24h, total domains 4. Backend Improvements: - /admin/zone-stats endpoint - Fixed zone-sync endpoints with correct imports
