Subject: [PATCH] feat(DirectorySearchQuery): Implementierung von
 DirectorySearchQueryHandler mit Eigenschaftsfilterung und Ergebnissammlung
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Aktualisierung von DirectorySearchQuery, um Eigenschaften zu akzeptieren und IEnumerable<ResultPropertyCollection> zurückzugeben
- Implementierung von DirectorySearchQueryHandler, um die Suche mit benutzerdefinierten Filtern, Bereichen und Eigenschaftsauswahl auszuführen
- Hinzufügen einer Logik, um nur angeforderte Eigenschaften zu laden, wenn diese angegeben sind
- Ersetzen von NotImplementedException durch die tatsächliche DirectorySearcher-Logik
