fix(medusa, admin-ui): Fix edit order variant stock (#3512)

The stock column when adding variants in an order edit would just look at `inventory_quantity`, location-unaware. Updated this to now attempt to request location-aware stock information and updated the column to use this information and show total stock across how many locations, and a tooltip showing per-location stock.
