Display end time instead of start time in Info Box clock widget

- Changed time display to show timeEnd (second time in range) instead of timeStart
- Clock now displays 14:22 instead of 14:07 when time format is '14:07 → 14:22'
- Falls back to timeStart if timeEnd not available, then to '12:00' default
