Once has been implemented, the Roles UI needs to be fixed to allow assigning fulfillment roles to users via any facility, not just warehouses.
Warehouses are defined here as facilities of facility type "warehouse".
In Fulfillment tab, Warehouse should be Facility and list all facilities.
Update UI label to rename "Warehouse" to "Supplying Facility"
Update UI dropdown to only show all facilities, not just warehouses (the dropdown allows searching if the list has more than 10 items, see attached screenshot)
Update any unit tests
Update any test cases to test any facility, not warehouses
The UI will not display facilities that are inactive
