Field Mapping profiles: For Holdings and Items, add validation for the "Staff only" field

Purpose: Inventory Holdings and Item records have notes fields which include a checkbox for staff only or not. If a field mapping profile is created, and no value is selected for the "staff only" checkbox, then the import will error. This story adds validation to that portion of the notes field in the field mapping profiles UI, to reduce the chance of making errors when creating or updating a field mapping profile.

As a staff person working with Data Import field mapping profiles
I want the staff only checkbox to be required for the Holdings and Item notes fields
So that I do not accidentally create faulty field mapping profiles
