FEATURE: Complete interactive network configuration for auto-installer

Enhanced network configuration with full user interaction:

WiFi Support:
- Automatic wireless interface detection using iw
- Network scanning with SSID selection
- Security protocol selection (WPA/WPA2, WEP, Open)
- Password input for secured networks

Ethernet Support:
- Automatic ethernet interface detection
- Interface selection from available options

IP Configuration:
- DHCP (automatic) or Static IP options
- Manual IP address, gateway, and DNS server entry
- Validation and configuration storage

Installation Integration:
- Network configuration applied to installed system
- Creates /etc/network/interfaces with user settings
- Configures DNS resolution for static setups
- Preserves WiFi credentials and settings

Package Dependencies:
- Added iw, wpasupplicant, dhcpcd5 for full WiFi support
- Maintains existing comprehensive wireless driver support

The auto-installer now provides complete network setup during installation,
configuring the target system with user-specified network preferences.
