feat(dnsmasq): SRV record so clients connect to mc.<domain> without a port

Browse Source 
Minecraft is a custom TCP protocol, not HTTP, so the no-port UX is solved with
a DNS SRV record (_minecraft._tcp.mc.<domain> -> :25565) rather than an HTTP
reverse proxy. Landing page now shows the bare address.
