Enhance Network Interface Detection and Configuration Management

- Implemented robust network interface detection with `GetInterfaces()` function
- Added validation for network interface names using regex patterns
- Updated `Network` struct to improve YAML tag formatting
- Modified `Gather()` and `SaveConfig()` methods to streamline network configuration
- Removed redundant `SaveConfig()` calls in various methods
- Added comprehensive network interface name validation logic
