Notify user if Special Schedule ends
Currently, if someone sets Notifications during a Facility's special schedule, the notifications eventually become inaccurate. Ideally, at the end of the Special Schedule's duration, a notification should pop up saying something like "$Facility_name's schedule just changed! You may need to reset your notifications."

- To get the time delta for scheduling it, you're gonna want to get the valid_end date for the SpecialSchedule, use a Calendar method to convert it to ms from epoch, then subtract the current time (in ms from epoch) from it.
