Lts/Viewer: Migrate CMakeLists.txt to Qt6 and add missing submodules

- Updated all CMakeLists.txt files to use Qt6:: libraries
- Added LtsFileDialog submodule (copied from qt5-before)
- Added LtsReportDisplay submodule (copied from qt5-before)
- Enabled both submodules in main Viewer CMakeLists.txt
- Qt5::Core/Widgets → Qt6::Core/Widgets in all Viewer modules
