feat(openvpn): add interactive subnet prompt in firewall config
Introduce an interactive prompt for specifying allowed subnets for VPN clients (10.8.0.0/24). The script now builds custom iptables rules based on user input and persists them via a systemd service, while retaining the original EasyRSA extraction and configuration.
