Configure and model install TUI tweaks (#3519)

The installer TUI requires a minimum window width and height to provide
a satisfactory user experience. If, after trying and exhausting all
means of enlarging the window (on Linux, Mac and Windows) the window is
still too small, this PR generates a message telling the user to enlarge
the window and pausing until they do so. If the user fails to enlarge
the window the program will proceed, and either issue an error message
that it can't continue (on Windows), or show a clipped display that the
user can remedy by enlarging the window.
