feat: enhance configuration management with main and route configs

- Added `main_config` and `route_config` fields to ActiveConfigResponse and AgentConfigResponse for better configuration handling.
- Updated NginxManager interface to accept separate main and route configurations.
- Modified sync service to apply main and route configurations correctly.
- Enhanced tests to validate new configuration fields and their application.
- Updated ConfigVersion model to include main configuration.
- Improved rendering logic for main and route configurations in the service layer.
- Added UI components to display main configuration changes and OpenResty parameter changes.
