Verbessere Benutzerkommunikation im ChatRoom durch optimierte Nachrichtenreihenfolge

- Füge Debug-Ausgaben hinzu, um den Ablauf beim Hinzufügen neuer Benutzer zu protokollieren.
- Sende wichtige Nachrichten (Raum- und Benutzerlisten) an den neuen Benutzer, bevor der checkerTask-Thread gestartet wird, um sicherzustellen, dass alle relevanten Informationen rechtzeitig bereitgestellt werden.
- Implementiere eine kurze Verzögerung, um den Abschluss des WebSocket-Handshakes zu gewährleisten, bevor Nachrichten gesendet werden.
