[3/3] update openapi spec: update code interacting with generated code

Adjusted C++ code to handle with new and renamed objects, as well as
properties with different types.

As a result of changing types, the QML side had to be updated as well.
I hope I found everything by manually testing.

Additionally, the Qt Quick application has been updated to test the
remote sessions more easily and to make it launch again.
