Don't show Programs button if programs are not configured

[arbrandes]

Description

On a bare installation one sees the Programs button even though no programs are configured in the backend:

The result is a 404 if you click it:

Expected behavior

If no programs are configured in the backend, the button should simply not show.

Implementation

While we could implement this as a config variable, ideally the frontend would detect whether programs are enabled and render the button based on that.
