Request desktop OpenGL compatibility profile at startup

Browse Source 
The visualization framework requires desktop OpenGL with the fixed-function
pipeline. Qt may otherwise create an OpenGL ES or core profile context on
some platforms (e.g. Wayland/EGL on Ubuntu 26.04), causing all 3D rendering
to fail with shader compile errors.
