refactor: Vereinfachung der SQLExecutor-Implementierung zur Rückgabe von IQueryExecutor

- Aktualisiert `SQLExecutor<T>` um `ISQLExecutor<T>` zu implementieren und `IQueryExecutor<T>` für die weitere Abfrageausführung zurückzugeben.
- Umstrukturierte Methoden zur Verwendung von `ToExecutor()` für die Konvertierung von rohen SQL-Abfragen in einen `IQueryExecutor<T>`.
- Geänderter Konstruktor, um `IServiceProvider` für die Injektion von Abhängigkeiten von benutzerdefinierten SQL-Abfrageklassen zu akzeptieren.
