Refactor and enhance service management

- Updated CMakeLists.txt to set CPACK_WIX_UPGRADE_GUID directly.
- Enhanced DependencyItem and DiagnoseWidget to manage service availability states.
- Implemented service management functions for Windows, including starting services and checking their status.
- Improved UI responsiveness in WelcomeWidget and NetworkDevicesToConnectWidget.
- Introduced SERVICE_AVAILABILITY enum to standardize service state representation.
- Cleaned up unnecessary code and comments across various files.
