CSM v1.23.0

CS2 Server Manager (CSM) release v1.23.0

Ready Up only. csm installs Ready Up, the native CS2 plugin, on every server. No Metamod, no CounterStrikeSharp.

MatchZy Enhanced is no longer installed. The legacy stack is gone: Metamod:Source, CounterStrikeSharp, MatchZy Enhanced, its MySQL/SQLite database setup, the doctor's database checks and the Docker step. Auto Tournament 3.x does not support MatchZy Enhanced; for Auto Tournament 2.x stay on csm 1.22.x or older.

Moving a host from MatchZy Enhanced: sudo csm self-update, then csm update-plugins (Ready Up on every server), then csm link to your platform. The old game/csgo/addons/ folders are no longer used: remove the Game csgo/addons/metamod line from each gameinfo.gi and delete addons/.

Also in this release: instance hosts without a backend setting run instances (#117).
