/**
 * @file test_z_proxies_integration.cpp
 * @brief Integrationstests für Z-Modul Bibliotheken mit Proxies-Modulen
 *
 * Diese Tests validieren die Integration der migrierten Z-Modul Bibliotheken
 * mit den migrierten Proxies-Modulen (Buildings, TrainingAreaBase, WirelessLocationSystem).
 *
 * Testfokus:
 * 1. NGLLogger Integration mit Proxies-Modulen
 * 2. NGLDB Integration mit Buildings/TrainingAreaBase
 * 3. NGLTools Integration mit Proxies-Services
 * 4. Cross-Module Type Safety (Qt6 types)
 * 5. Build System Integration (CMake targets)
 *
 * Build Integration:
 * - These tests are included in the --integration-test flag pattern
 * - Pattern: test_z_* matches this file
 * - Requires: BUILD_GROUP4=ON for Proxies modules
