feat (TUI): Print Client Summary

[nynymike]

When we are asking a Jans admin to share the client config, it would be nice if there was a way to export all the client metadata into one file. It would be nice if we had a field to "Export Summary" which gathered all the client config that has values, and writes it to a text file like client_name.txt (replace any spaces with _...). This file should be written to the filesystem.

@nynymike There is a way to save client information. On the client list, press key d , you will see json representation of client, you can save it by using Export button. See the following video

There should be a hint in the bottom left of the corner: d - View / Export JSON

A keybinding s should save summary of client as described above rather than using view/export.
