feat: Add AIVPN support and enhance client statistics tracking

- Introduced AIVPN server detection and statistics fetching in ServerMonitoring.
- Implemented AIVPN client statistics handling in VpnClient, including raw and offset counters for traffic.
- Enhanced AWG parameters to include S3 and S4.
- Updated database schema to accommodate new AIVPN statistics fields.
- Added a script for remote reset and reinstallation of protocols.
- Improved client view template to ensure proper display of connection instructions.
- Added translations for connection instructions in multiple languages.
- Ensured host-level NAT for AWG subnet in VpnServer.
