feat(scheduler): add pagination to skipped jobs and filter manager start events

- Implement pagination for skipped jobs display with 20 items per page
- Add pagination controls (previous/next buttons) to the scheduled jobs view
- Exclude ScheduledJobManager "started" events from run logs, keeping only "completed" events
- Add ShouldBeEncrypted interface to ScheduledTaskJob for secure queue handling
- Update log filtering to fetch 500 recent skips and slice for pagination
- Use Log facade instead of fully qualified class name
