feat(site): enhance monitoring, domain, and system tracking

- Improve domain lookup by adding CNAME and SRV record support
- Enhance domain status logic to include expiry and DNS resolution verification
- Update monitoring API to perform synchronous initial checks for immediate status updates
- Refactor site UI:
    - Add tag filtering to domains and monitors tables
    - Improve calendar view with better visual indicators for today and events
    - Update monitor detail view with improved status badges and pending states
    - Simplify home page layout by removing redundant card wrappers
- Update localization files for numerous languages to support new UI elements
- Add `cleanEndpointsConfig` to hub to safely reuse Docker network settings during container updates
