In this commit we modify the ClosePosPopup
so that we make it more usable.
For this reason we expose less info in order
to keep it simple for the user and we rename
the footer buttons respecting the Odoo standards.
Finally, since we want to make it more obvious
to the user and avoid unwanted acceptance of the
payment difference, we show ConfirmPopup with the
relevant information.
