BUILD_RTI=OFF: 1902/1902 Targets erfolgreich, DDS-Stubs vervollständigt

Neue Stub-Header für BUILD_RTI=OFF Konfiguration:
- include/DDS/Generic/generic_base.h: Topic-Name-Templates, Helper-Funktionen
- include/DDS/Generic/generic_logger.h: Logger-Wrapper mit DataType-Enum
- include/DDS/Generic/ddsgen_export.h: Export-Makros (leer für OFF)
- include/DDS/Generic/generic_data_reader.h: Data Reader Template-Stub
- include/DDS/DTC/generic_dtc.h: Minimale DDS-Typen für DTC
- include/LtsUtils/LtsUtilsCore/data_modification_enum.h: DataModification Enum
- include/FileManagement/flm_dtc_impl.h: Virtuelle Methoden für Name-Helper
- include/OperatorManagement/opm_dtc_impl.h: DtcImpl ohne Q_OBJECT

Wichtige Änderungen:
- QObject-Basisklasse entfernt für DatabaseInterfaceImpl und DtcImpl (BUILD_RTI=OFF)
- Logger-Stub verwendet Qt-Logging (qDebug/qWarning/qCritical)
- FileStatus als int-Alias statt enum class für BUILD_RTI=OFF
- CMake: DDS-Bibliotheken als leere INTERFACE-Targets für BUILD_RTI=OFF
- std::optional: is_set() → has_value(), get() → value()
- QList → std::vector Konversionen korrigiert
- qAsConst-Fehler mit rvalue expressions behoben

Build-Status: 1902/1902 Targets erfolgreich (BUILD_RTI=OFF)
Tests: Nicht ausführbar ohne RTI Connext DDS (BUILD_RTI=ON erforderlich)
