* fix: delete generated designerExample_*.py files
designerExample.py loads designerExample.ui directly
* remove unused examples/utils.py
* add almost all examples in folder
* use mkQApp and don't set style nor palette
not needed for an example and also avoids a PyQt6 6.0 refcount bug in
app.setStyle()
* bold interesting examples
* test_examples.py needs to know about Namespace too
* Revert "remove unused examples/utils.py"
This reverts commit 2eddead459.
* categorize examples lists in utils.py
