Fixing some CI errors and addressing a code review comment.

After a few attempts, I couldn't make the app work with jQuery 4.x. bootstrap-select is not compatible with jQuery 4.x. I tried a bunch of things but removing that dependency breaks the search on when generating case reports. So we need to handle that prior to updating jQuery.

I am not super familiar with jQuery to try to add a patch here, but that could be an alternative to finding a replacement to bootstrap-select. Although I imagine patching it would become a problem sooner or later given that the last update was 4 years ago, and finding an alternative that is compatible with jQuery 4 might be better.
