Änderungen:
- Integration des neuen Modells TaxiMapTileHouse zur Verwaltung von Häusern auf der Karte.
- Anpassung der TaxiMap- und TaxiMapService-Logik zur Unterstützung der Hausplatzierung und -verwaltung.
- Erweiterung der Benutzeroberfläche in TaxiToolsView.vue zur Erfassung und Anzeige von Hausinformationen.
- Implementierung von Methoden zur Speicherung und Aktualisierung von Hausdaten in der Datenbank.

Diese Anpassungen verbessern die Funktionalität und Benutzererfahrung im Taxi-Minispiel, indem sie eine detaillierte Verwaltung von Häusern auf der Karte ermöglichen.
