Add Avalonia server-host launcher (MVP scaffold)

Cross-platform C# GUI to replace the Qt/C++ Host GUI, on the same dotnet toolchain as the server. MVP: load/save commonwealth-server.json, Start/Stop the CommonwealthOnline.Server process (published exe, then dll, then source run), and stream its output to a live log. Themed to the Commonwealth Online brand (near-black + amber). Builds clean on net8.0. Next: player list + kick/ban via the admin port, then retire the Qt host.
