A new Activity tab should be added to the work item/page view, displaying the activities performed for that page. It should support filtering by approval name, step name, originator, decision, and date.

On the approvals list, add an icon that allows reviewing the activity for a given approval. This will display the activity list filtered for the selected approval. A back link should be available to return to the approvals list with the previously applied filters preserved. If the filters on the activity list are modified, the back link should no longer be available.
