Comment 2 for bug 2030820

Working branch user/jeffdavis/lp2030820-scope-line-item-alert-type has a potential fix:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/jeffdavis/lp2030820-scope-line-item-alert-type

To test, add some alert types to acq.lineitem_alert_text belonging to various org units (say, BR1 and BR3). Then go to Purchase Orders, do a search, and click on "Notes and Alerts" for one of the lineitems. The Alert Type dropdown should contain only alert types belonging to ancestors of your current workstation OU.
