Revise the Orders search results list columns

Overview: When search results display for PO searches and filters, this story describes what columns and data should appear

Scenarios

1. Scenario 1
   • Given the Orders app landing page
   • When a user searches or filters for POs
   • Then the results pane should include the following columns:
     • PO number
     • Vendor [display the vendor code, not the vendor name]
     • Status
     • Order type
     • Last updated [date only, no time]
     • Acquisitions unit [previously Owner] (DB: Must be split out into separate issue)
     • Assigned to
2. Scenario 2
   • Given the PO search results list
   • When a user first switches from the POL toggle to the PO toggle
   • Then the results list should be filtered to only display POs that are
     • Pending or Open
     • Which means that POs that are Closed are not displayed by default
3. Scenario 3
   • Given the PO search results list
   • When a user views the PO search results list
   • Then the user should be able to sort the results list ascending and descending by clicking on the following column headers
     • PO number
     • Status
     • Order type
     • Last updated
   • And the default sort order should be descending by PO number (numerics descending, then alphas descending)
   • Note: sorting for the Vendor, Acquisitions unit, and Assigned to columns will be handled separately, in story UIOR-308. For those 3 columns, suppress the up/down sort arrow next to the column header.
