feat(dns): Implement DNS management functionality

- Added DnsManager and DnsEntry classes to handle DNS entries.
- Introduced new interfaces for DNS entry requests and data structures.
- Updated Cloudly class to include DnsManager instance.
- Enhanced app state to manage DNS entries and actions for creating, updating, and deleting DNS records.
- Created UI components for DNS management, including forms for adding and editing DNS entries.
- Updated overview and services views to reflect DNS entries.
- Added validation and formatting methods for DNS entries.
