Allow beta-typed Modrinth builds for EasyAuth (easyauth:beta)

EasyAuth publishes its 26.x builds as beta on Modrinth, and the itzg
resolver only accepts release-typed versions by default, so the mc
container failed to start. Pin easyauth:beta in the default mod list and
teach the panel's mod manager to compare entries by base slug so version
qualifiers don't break protected/duplicate checks.
