Enables recurring scheduled event completion

Extends scheduled event completion to support recurring events.

The changes introduce the concept of an "occurrence" for recurring events,
allowing users to mark individual instances of a recurring event as complete.
This involves:
- Adding recurrence information to the ScheduledEvent model.
- Modifying completion logic to handle recurring events with daily/weekly frequencies
- Updating UI to display recurrence information and mark individual occurrences as complete.
