Cross Department Sales Total on WPR

Another request has been to have the WPR for SambaPOS V4 show cross department sales like V2, where one department would settle a ticket from another department, the WPR would show this breakdown in the Sales figures.

I know this can be calculated from sales and income, but V2 was a bit neater for the office staff to understand.

If these are not too urgent I’ll start changing reporting infrastructure as soon as I complete current payment processing thing. If we start it after new infrastructure is ready we can save double work.
