- Replaced viper calls with utility functions in GetSystemInfo to improve code clarity and maintainability.
- Added a new system.go file with utility functions for retrieving system version and edition information.
- Enhanced PrintLogoWithWelcomeInfo to include detailed system information, improving user experience during server startup.
- Updated output formatting for better readability and consistency in welcome messages.
