fix(schedules): correct event watch schedule end time to 22:00

The scheduled job for watching events was previously set to run until
hour 23. This changes the `nodeSchedule.Range` end hour from 23 to 22
to ensure the job stops execution correctly before the end of the day.

This is a bug fix to align the actual execution window with the intended
operating hours.

No breaking changes.
