Qt6 migration: LtsWidgets API fixes, LtsWebSocket logger init, RTI Docker install

- LtsWidgets: Fixed Qt6 API compatibility issues
  - QWheelEvent::delta() → angleDelta().y()
  - QStyleOption::init() → initFrom()
  - QComboBox activated signal signature change
  - QTextCodec removal (UTF-8 default in Qt6)
  - Missing widget includes added

- LtsWebSocket: Fixed m_logger reference initialization
  - Added NGLLoggerBootstrap includes
  - Proper initialization in constructor initializer lists

- CMake: Added BUILD_LTSWEBSOCKET option for temporary exclusion

- Docker: RTI Connext permanent installation script added
  - ci/install-rti-in-docker.sh for persistent RTI setup
  - Removes need for volume mounting RTI into container

- BUILD options: FilterManagement, RTI, Codification, Grantlee, LtsWebSocket
  can be disabled for partial builds during migration
