Fix CloudFlare DNS Management: Filter main domains only, auto-delete DNS records on domain removal, improve table display

- Filter domain dropdown to show only main domains (exclude sub-domains)
- Add automatic CloudFlare DNS record deletion when domains/sub-domains are removed
- Improve DNS Records table display to match SSH Logins/Logs table styling
- Add loading states and proper table structure with ng-if conditions
- Update CSS to match activity-table styling with sticky headers
