- #include <QObject> zu 106+ Header-Dateien hinzugefügt (Qt6 benötigt explizites Include) - ui_requirement.h/cpp zu requirement_widget.h/cpp umbenannt (vermeidet AutoUIC-Scan) - CMakeLists.txt aktualisiert - Qt6Positioning-Dependency in Dockerfile hinzugefügt Fixes: - AutoUIC-Fehler bei AesBaseGui (requirement.ui nicht gefunden) - QObject-Missing-Include-Fehler in Qt6 - Qt6Location-Modul nicht gefunden (qtpositioning fehlte)
