- Add nftables as a third firewall backend option alongside firewalld and iptables - Detection priority: firewalld → nftables → iptables (legacy fallback) - Uses dedicated `openvpn` and `openvpn-nat` tables for clean isolation - Integrates with native `nftables.service` via include in `/etc/nftables.conf` Closes https://github.com/angristan/openvpn-install/issues/530
