fix(widget): stop tomorrow's events from stretching today's grid bounds

calcGridStart/calcGridEnd only looked at hour-of-day, so a tomorrow
event's early or late hour could inflate today's grid range with empty
rows, pushing the non-scrolling TomorrowSection below the widget's
visible area. Filter to today-only events before computing bounds.
