fix: add network manager GUI and manual network configuration

Browse Source 
- Add networkmanagerapplet for GUI network management in GNOME
- Add network status checking to bash initialization
- Add network_help function for manual configuration guidance
- Create comprehensive MANUAL_NETWORK_SETUP.md documentation
- Update ISO label to workshop-friendly name
- Fix NetworkManager configuration for live ISO

This resolves the issue where network manager was not accessible
in the live USB boot environment and provides fallback options
for manual network configuration when internet is not available.
