Enables marking scheduled events as complete

Implements a feature to mark scheduled events as complete, replacing the checkbox with a button for improved UX.

This commit enhances the Scheduled Events functionality by allowing users to mark events as complete. It also includes:

- Replaces the checkbox with a "Mark Complete" button for better usability.
- Adds logging for debugging purposes during event completion toggling.
- Routes completion events (kind 31925) to the ScheduledEventService.
- Optimistically updates the local state after publishing completion events.
