Add Lts/Application module with Qt6 CMakeLists updates

- Copy Lts/Application from qt5-before (AarApp, OpApp, THP submodules)
- Update all CMakeLists.txt to use Qt6::Core, Qt6::Widgets, Qt6::Xml, Qt6::Network, Qt6::PrintSupport, Qt6::Svg, Qt6::WebEngineCore, Qt6::WebEngineWidgets
- No SIGNAL/SLOT, QRegExp, QDesktopWidget, or QTextCodec issues found in Application source code
- Module ready for Qt6 build validation
