calendar: events didn't show up on last week day.

  - On the calendar view, events starting on the last day of the week didn't
    show up. CanvasEventView.set_range() didn't treat `end' (datetime.day) as
    inclusive, so week ends badly on DATE(last_week_day, 00:00:00), insteaf of
    DATE(last_week_day, 23:59:59)
