Add Entity History Card

As far as I can tell (although I may be wrong), the "sample history" as a workflow will not work due to circular references. We have the convention of having activities (any subclass of Activity) reference entities (any subclass of Entity) and NOT the other way around.

Instead I suggest that we introduce a "History" card on the overview page of any section that subclasses Entity (e.g. Instruments, CompositeSystems, and Collections). This "History" card would be a curated view of the current "Referenced by" card:

Where we would only list sections which subclass Activity (e.g. Processes, Measurements, and, Analysis) in the order of their datetime property.
