Show Items on Order in Inventory History

[atcrawf]

We're a bookstore running our inventory on Square. It would be extremely helpful to be able to see if a particular book is already part of a pending purchase order on that book's item details page.

This would allow us to:

-give customers accurate estimates of when a book will be back in stock

-prevent us from double-ordering an item on more than one PO

I hope this would be an extremely straightforward fix, since all the information already exists!
