Fix frontend to use series endpoint for single occurrence modifications
- Extended update callback signature to include update_scope and occurrence_date parameters - Modified app.rs to detect when series endpoint should be used vs regular endpoint - Updated calendar_service to automatically set occurrence_date for "this_only" updates - Modified all callback emit calls throughout frontend to include new parameters - Week_view now properly calls series endpoint with "this_only" scope for single occurrence edits This ensures that single occurrence modifications (RecurringEditAction::ThisEvent) now go through the proper series endpoint which will: - Add EXDATE to the original recurring series - Create exception event with RECURRENCE-ID - Show proper debug logging in backend 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
