Events - Prohibit selection of a date for which the event is already scheduled

As an operator I want to be prevented from adding a duplicate event to a day for which that event is already scheduled so that my forecast behaves as expected when reversing the event

Notes

  • Manual Event

• When a date is selected that already has the same event (name and type) scheduled, display and error message below the date field and disable the buttons that allow the user to advance
• 
• Verbiage: This event has already been scheduled for this date, please select a different date.
