Refaktorisierung: Absicherung von DB-Operationen und Verbesserung der Geschäftslogik

- Implementierung von LINQ-Abfragen innerhalb der Core-Bibliothek zur Minderung von SQL-Injection-Anfälligkeiten für DB-Operationen von Umschlägen und Empfängern.
- Aktualisierung der Geschäftslogik in der Service-Schicht für verbessertes Transaktionshandling.
- Erweiterung der ServiceMessage um eine neue Flag-Funktion zum Verfolgen von Cybersecurity- und Datenintegritätsproblemen.
- Hinzufügen spezifischer Benutzerverhaltensflags zur besseren Erkennung und Behandlung potenzieller Datenverletzungen.
