Forecast Edits - Display the user and time when an edit was last made made

As an operator I want to see the details of the last manager edit that was made to my forecast so that I have a better understanding of who monkeys with what!

Business Use Case
Forecasting changes are done on a regular basis and are evaluated on the Forecast Evaluator in InFORM. Although the Forecast Evaluator shows that the forecast has been edited, it does not indicate which user in the restaurant made the update. For better visibility and accountability, the field “Restaurant edited” should indicate the user that last made the edit and at what date and time the edit was made.

Notes

• Display the following: "Forecast edited by {} on {}", where first placeholder is the User (first and last name), and second placeholder is the full timestamp edit was made (month/day/year hour:min:sec) , in the store's local timezone
• Mockup, from Ben
