chore: support Qt6 (#385)

- Update CMakeLists.txt to support both Qt5 and Qt6
- Replace DApplicationHelper with DGuiApplicationHelper for Qt6
- Update debian/control and debian/rules for Qt6 compatibility
- Fix Qt6 compatibility issues in various widgets and utilities
- Update unit tests for Qt6 support
