add version number to the settings menu or console

as I use the platform more and more I’d love to be able to see the versions of the various sub systems throughout. Not like overall version 3.6 but executor 3.6 notifications 3.6 etc

No files, tests, or entry points are named. First locate how the settings menu and console are implemented, then determine how subsystem versions are currently defined and exposed. Done means users can view separate version numbers for components such as the executor and notifications, rather than only the overall platform version.
