Show total order amount

[wvengen]

Currently in Foodsoft, the order's total amount is shown. This helps to see if the minimum order amount is reached. This feature is missing from foodsoft-shop (picked up from foodcoops/foodsoft#260 (comment)).

As a user story, I would be thinking of something like this: as a foodcoop member, I would like to know whether the minimum order amount was reached, and how far off we are, so that I can order more to reach it and know whether it is likely that I will get what I ordered.

In foodsoft-shop, this is quite different, because articles from all orders are shown together, so there is no single amount. So we could have a minimum order amount as part of the supplier, and then show a warning if this is not reached for one of the orders (perhaps with an extra indication in or near the last-box-filled bar for the affected articles).

Another option would be to add a warning-icon to the suppliers on the left. A tooltip could show the details.
Also, when a supplier is selected as a filter, a box could be shown above the order articles, showing the supplier name and the required minimum order amount (and progress, when available).
