[BE] VSA - Change sort attribute to name
In !60793 (merged) we have added sorting to VSA stage tables.
We discovered a potential usability issue: Clicking on the Issue
column will not sort by name. Instead, it will sort by end_event
(see this discussion for details).
Let's change the sort attribute to the name of the related item (could be an issue, a MR, etc. depending on the active stage).
