Simplify main, use version from meta-data defined in CMake

* Simplify code
* Set meta-data for Qt application via helpers from c++utilities and
  qtutilities
* Set sensible default settings for Qt via helper from qtutilities for more
  modern behavior regarding High DPI scaling and theming, e.g. for better
  dark mode support under Windows 11
