BUILD_RTI guards for DDS/Routing modules + logger init fixes

- Lts/DDS: Add BUILD_RTI guards to pacemaker.h, dds_connector.h,
  generic_fts_* files, generic_base.h, routing_plugin.h
- Lts/Services/RoutingServiceNG: Add BUILD_RTI guards to session.h/cpp,
  connection.h/cpp, data_writer_task.h/cpp
- Fix C++23 reference member initialization: use getLogger() instead of
  getNGLLogger() in constructor initializer lists
- Root CMakeLists.txt: Add Lts/DDS to include_directories
- Fix export header generation order (GENERATE_EXPORT_HEADER before
  TARGET_INCLUDE_DIRECTORIES)
- Remove auto-generated stub files (external deps collected separately)
