[IMP] point_of_sale: cash closing difference visible

When a pos session is closed, the difference and transactions of cash
control are not good anymore, because it is based on the statement
linked to the cash payment method, and it is modified during the
validation of the session to create a balanced account move.

So we are now storing the values in fields, to keep history of the
closing control
