When a recurring event has a modified occurrence, the calendar was showing both the original and modified versions. This happened because the code didn't properly handle RECURRENCE-ID exceptions in iCal data.
Changes:
- Modified extractScheduleEventsInRange() to collect exception events first and filter them from recurring patterns
- Updated expandEventOccurrences() to skip dates that have exceptions
- Applied same fix to extractScheduleEvents() for proper date range filtering
Fixes issue where modified recurring events appeared twice in the UI.
