feat: Premium infrastructure improvements

1. Parallel Zone Downloads (3x faster)
   - CZDS zones now download in parallel with semaphore
   - Configurable max_concurrent (default: 3)
   - Added timing logs for performance monitoring

2. Email Alerts for Ops
   - New send_ops_alert() in email service
   - Automatic alerts on zone sync failures
   - Critical alerts on complete job crashes
   - Severity levels: info, warning, error, critical

3. Admin Zone Sync Dashboard
   - New "Zone Sync" tab in admin panel
   - Real-time status for all TLDs
   - Manual sync trigger buttons
   - Shows drops today, total drops, last sync time
   - Health status indicators (healthy/stale/never)
   - API endpoint: GET /admin/zone-sync/status
