fix(irc): use short name for unrealircd in anope + thelounge configs

Same CoreDNS iamworkin.lan template + ndots:5 hijack as the irc-notify fix.
Anope services (nickserv/chanserv/memo) have been disconnected from unrealircd
for weeks ("Host is unreachable" every 3s). Thelounge server defaults pointed
at the same broken FQDN.

Short name unrealircd.irc.svc resolves to the ClusterIP directly.
