ediblerope dfbc727f5f Disable EAC on 7DTD server so Proton clients can connect
Proton-based clients (e.g. CachyOS native install hitting 7DTD via
the Proton runtime) fail EAC handshake against a Linux dedicated
server. Disabling server-side lets Proton clients join via the
"Play without EasyAntiCheat" splash option.
