Refactor fun commands to external module

Commented out fun command implementations (noclip, godmode, freeze, unfreeze, resize) in funcommands.cs and removed their registration from RegisterCommands.cs. These commands are now intended to be provided by the new CS2-SimpleAdmin_FunCommands external module, improving modularity and maintainability.
