fix(calendar): display ICS badge events in calendar views

Previously, ICS events with showType="badge" were being filtered out
completely from the calendar display due to an early return statement.
This prevented badge events from appearing in any calendar view.

The fix removes the blocking early return and instead includes badge
events in the main events array with a badge property to maintain
their special rendering requirements.

Changes:
- Add badge property to CalendarEvent interface
- Remove early return that blocked badge event processing
- Include badge events in main events array with badge flag
- Maintain badge event caching for performance
