When an attendee accepts/rejects/tentative a recurring event with
exceptions, only update the PARTSTAT without removing exception events.
Add removeOverrides: false parameter to updateSeriesAsync call in
handleRSVP function to preserve all recurrence exceptions.
Fixes: Recurrence exceptions being deleted when accepting/rejecting
all events in a recurring series
* fix: update PARTSTAT on all VEVENTs when RSVP to recurring events
When an attendee accepts/rejects/tentative a recurring event with exceptions,
update PARTSTAT on ALL VEVENTs (master + exceptions) to reflect the correct
attendance status across the entire series.
Changes:
- Add updateSeriesPartstat() in EventApi.ts to update PARTSTAT on all VEVENTs
- Update handleRSVP() to use new function instead of updateSeriesAsync
- Preserve exception times while updating PARTSTAT consistently
- Update test to verify new function is called correctly
Fixes: Exception events not accepting when user chooses 'Accept all events'
