fix(game): aktualisiere Handkarten nach gespieltem Slip

In allen betroffenen ViewModels wurden die mit [ObservableProperty] markierten Felder entfernt und durch public partial Properties mit { get; set; } ersetzt. Property-Namen wurden vereinheitlicht (z.B. IsChallengeVisible, PendingChallenge, SyncStatusText). In LobbyViewModel.cs wird nun geprüft, ob alle Spieler bereit sind, bevor das Spiel gestartet werden kann (CanStartGame). Die Behandlung von StateChanged-Messages aktualisiert relevante Properties. In SlipItIn.csproj wurde das WarningLevel für alle Konfigurationen explizit auf 1 gesetzt.
