Add WireGuard, DNS and more to the web UI and router-setup

Web UI: a WireGuard page (tunnels, peers, keys made on the router, client configs with a QR code, import of wg-quick configs, live status), a DNS page (records, wildcards, forward zones), interface dropdowns with VLAN devices, IPv6 options and a local domain. router-setup asks about VLANs, IPv6 and the domain. The router publishes its own name in DNS and hands the local domain to DHCP clients; wg and jq are on the router. Includes a script that takes over antigua's tunnels.
