+ * @file test_z_application_functionality.cpp
+ * @brief Anwendungsfunktionstests mit Z-Modul-Bibliotheken
+ *
+ * Diese Tests validieren die Anwendungsfunktionalität unter Verwendung
+ * der migrierten Z-Modul Bibliotheken in realistischen Szenarien.
+ *
+ * Testfokus:
+ * 1. Logger-Funktionalität in Anwendungskontext
+ * 2. Datenbankoperationen mit NGLDB
+ * 3. Settings-Management mit NGLSettings
+ * 4. Übersetzung mit NGLTranslator
+ * 5. Kompression/Dekompression mit NGLCompression
+ * 6. Netzwerkkommunikation mit TCPServer
