- readNetworkStatus() now returns array of all interfaces instead of single string
- Parses 'ip addr' output (with ifconfig fallback) for all IPv4 interfaces
- Each interface classified as LAN / VPN / Public by name and IP range
- VPN detected by interface prefix: wg*, tun*, tap*, vpn*
- RFC1918 ranges (192.168.x, 10.x, 172.16-31.x) shown as LAN
- Display: icon + IP + interface name badge + type label per row
- Handles NAT servers showing both local LAN and VPN IPs simultaneously
