[VSA] Active stage items should not include Closed items (BE)
Summary
#299265 (closed) adds BE changes to filter Issues/MRs that have not reached a stage end event so that we can show a list of items that are still in a selected stage.
Problem to solve
Users want to view a list of items still in a stage so that they can identify which items require action in order to move them on to the next stage. As a user with this JTBD, I don't want to see Closed Issues/MRs in this view because they are not relevant to my JTBD.
Proposal
Per @ahegyi's suggestion, add filters to remove Closed Issues/MRs from the list of items that haven't reached an end event.
