Loaded scripts: session and folder should be a bit more distinguishable

Refs: #64230 In the loaded scripts view if I am debugging multiple sessions how we display sessions and folders is not distuingishable enough. Currently they have these two distinctions: * sessions do not show a folder icon (which is great, but not visible in the default icon theme) * sessions have a differetn hover text I suggest to experiment with prefexing the session title with `Debug Session` Or to try to prefix the folder label with `../` if that makes sense. Any other ideas polish that would make them more distungishable would be good imho
