As a user who can edit an activity I should be able to drag and drop an activity calendar event to a new date in order to quickly change the date settings for the activity (Optional)

Confirmations

• This should work for all core plugins, but if contributed plugins have not been updated to add this functionality then the event should not be draggable
• The setting for the activity that is modified will be the one that was displayed in the calendar
• The activity must validate that the new date is a valid setting. If is not an error should be displayed and no changes will be made to the activity.
• If the user does not have the required capability to manage the settings for the activity, the event should not be draggable
• If the event that is dragged corresponds to an override, it should not be draggable
• The user should see a confirmation modal explaining exactly which setting will be modified and be asked to confirm the change.
• The time of day will remain the same.
