Randomization and kit stability improvements

You can now remove a kit from all visits (former known issue)

Study designers: On the Kits tab, in the Add Kit to Schedule dialog box, when you deselect all visits associated with a kit type, and click Save, the kit type is removed from all visits. Previously, whenever you deselected all visits associated with a kit type, the kit wasn't removed from all visits. (Issue 30372988)

Retracted workaround: You no longer have to remove each kit type individually from each visit in the schedule. However, we still recommend you run the Study Design report to make sure the kit type was in fact removed from all visits.
