Add Ongoing to the POL filters

Purpose: To add the value of Ongoing for the Receipt status and Payment status POL filters

User story statement(s):

As an acquisitions staff member working with ongoing orders
I want to be able to filter PO lines by the Ongoing status
so that I can more easily find the orders that I need to work on

Scenarios:

1. Scenario 1:
   • Given the POL search/filter pane in the Orders app
   • When viewing the options for Receipt status and Payment status filters
   • Then the value Ongoing should appear in the list of values under each filter, in alphabetical order with all the existing values
2. Scenario 2:
   • Given the Ongoing value in the Receipt status and Payment status filters
   • When a User selects it
   • Then any POL search results should be filtered by that value
