Backend für "Slip It In" mit ASP.NET Core erstellt
- Neues Backend-Projekt mit Entity Framework Core (PostgreSQL) und geteilten Modellen/DTOs angelegt - Datenbankstruktur und Migrations implementiert (User, Game, Player, Phrase, PlayerCard, GameRound, SlipChallenge) - SignalR-Hub für Spielkommunikation (Lobby, Spielstart, Kartenvergabe, Slip/Challenge) hinzugefügt - Spiellogik und DB-Zugriffe im GameService gekapselt - JWT-Authentifizierung und CORS für Entwicklung konfiguriert - Projektdateien, NuGet-Abhängigkeiten und .gitignore aktualisiert - Startkonfiguration und Umgebungsdateien angepasst
