Qt6 Migration: Complete migration with DDS/RTI support and build validation

Major Changes:
- Merged latest Qt5 devel content from dlbo (292 files changed, 7 new dirs)
- Consolidated forward-declarations and include folders
- Removed unneeded modules per Niklas' repo check list

Build System Fixes:
- Fixed CMake VERSION_GREATER syntax in ParticipantManagement/CMakeLists.txt
- Added VLC packages (libvlc-dev, vlc-plugin-base) to docker_build.sh
- Added PostgreSQL dev packages (libpq-dev, postgresql-server-dev-all) to Dockerfile
- Fixed locale warnings (ANSI_X3.4-1968 → C.UTF-8)
- Fixed ArcGIS SDK path warnings when BUILD_ARCGIS=OFF

Code Generation Fixes:
- Fixed IDL enum collisions (PortType→CorePortType/DdsutPortType, PdmEventType)
- Fixed Grantlee template svc_translation.cpp.grantlee:
  - Changed {{ idl_enum.name }}_def:: to {{ idl_enum.name }}::
  - Fixed .underlying() calls for C++11 scoped enums (enum class)
- Removed generated files from repo (moc_*, *_dtc.h, *_ftc.h)

Validation:
- BUILD_RTI=ON: SUCCESS
- BUILD_RTI=OFF: SUCCESS
- C++17 standard maintained for RTI 7.7 compatibility
- Ubuntu 26.04 Docker environment verified

Remaining Warnings (expected):
- BgViewer, KDChart, KDReports, Poppler-Qt6 not found (optional features)

+- transfer data from SHM to Map.
+
+ ArcGISQt5Hack
+   - Some ArcGIS versions are using a qt version which requires an sysmbol 'operator delete()' which is missing in out qt.
+     So try to 'emulate'
+
+ Common
+   - Common elementes like IdHandler, ReferencePointer, Logging, export macros etc.
+   - Have to be a sperate lib to avoid circular dependencies
+
+ GeometryModel
+   - Classes to define a set of graphics drawn in one layer, like a plan
+ 
+ GraphicalObjects
+   - Graphical primitives to render with ESRI RuntimeQt-Library
+
+ FunctionDialog
+   - Dialog for debugging purpose
+
+ GraphicalObjects
+   - GraphicalObjects are used in MapImpl
+
+ Map
+   - Interface of common map
+
+ MapImpl
+   - Implementation of 'Map'
+
+ MapObjects
+   - Interface to define objects on the map
+   - Consisting of one or more GraphicObjects
+
+ MapObjectsImpl
+   - Implementation of MapObjects
+
+ MathUtils
+   - Mathematical utils like clipper, PathRasterer, SimpleHelper, Spline
+
+ ModuleTests
+   - ModuleTest of Interface (with GUI)
+
+ Resources
+   - Some resource files like
+   - 'pushPinRedClipArt.png' (http://www.clipartbest.com/clipart-jixEoBAdT)
+   - ..
+
+ Rubberbands
+   - Interfaces (and implementations) of rubberbands to handle input of geometries
+
+  SideBar
+   - Implementation of a sidebar widget on map
+
+ Symbology
+   - Interface of 'Symbology'
+
+ SymbologyGui
+   - Gui Interface to use Symbology in Dialogs and Views
+
+ SymbologyImpl
+   - Implementation of 'Symbology'
+
+ Tests
+   - initial executable (to test the library)
+
+ UnitTests
+   - UnitTests (also of internal classes), uses static version of situationMap (libsituationMap_static.a)
+
+ UserInterface  - currently unused
+   - Ui files 
+
+ Utils
+   - Utilities, e.g. MouseMoveLayer

+You can execute the example within the build dir. Therefore the props files are
+copied using a construction like this:
+  SET(LOG4CXX_PROPS_FILE log4cxx_sitmapMain.props)
+  ADD_CUSTOM_COMMAND(TARGET sitMapExample POST_BUILD
+                     COMMAND ${CMAKE_COMMAND}
+                        ARGS -E copy_if_different ${CMAKE_CURRENT_SOURCE_DIR}/${LOG4CXX_PROPS_FILE} $<TARGET_FILE_DIR:sitMapExample>/${LOG4CXX_PROPS_FILE}
+                    )
+But then the props file is only update if a cpp or h file is modified and the lib has to be rebuild.
+Therefore links are useful:
