UTC midnight passed to FullCalendar's timeZone:'local' was being converted to local time, shifting all-day events back by 1+ days for users in UTC-X zones. The edit form had the same bug via new Date(). Fix: pass YYYY-MM-DD slices (UTC date) for all-day events in both toFcEvent and EventSlideOver resetForm, bypassing timezone conversion.
