[keyboard] Move remaining variables to Config

- Config already *has* everythind, but drop the useless copies
  and duplicated code from the Page
- Plug the models model into the Page
- While here, document the model / layout / variant distinctions

The code doesn't fill the UI properly, and the drop-down
for the models combobox is not right, but at least the data
is shared.
