feat: Anpassung der Datenbankmodelle zur Unterstützung von snake_case und Einführung von freezeTableName

- Aktualisierung der Modelle in verschiedenen Bereichen, um die Feldnamen im snake_case-Format zu verwenden.
- Hinzufügen der Option freezeTableName zu den Modellen, um die Tabellennamen in der Datenbank unverändert zu lassen.
- Verbesserung der Konsistenz und Lesbarkeit des Codes durch einheitliche Namenskonventionen.
