Füge Unterstützung für das Neuladen von Räumen aus der Datenbank hinzu

- Implementiere die Methode `reloadRooms` in den Klassen `Server` und `SSLServer`, um Räume aus der Datenbank neu zu laden.
- Ergänze einen Signalhandler in `main.cpp`, um das Neuladen der Räume bei Empfang von SIGUSR1 zu ermöglichen.
- Füge die Methode `getRooms` in der `Database`-Klasse hinzu, um Räume aus der Datenbank abzurufen.
- Aktualisiere die Header-Dateien entsprechend, um die neuen Methoden zu berücksichtigen.
