Resolves the same "Failed to fetch" cancellation issue that was occurring in the "modify single event in a series" flow by eliminating concurrent HTTP requests from the frontend. ## Problem: The RecurringEditAction::ThisEvent handler was making two concurrent requests: 1. UPDATE request via update_callback.emit() 2. CREATE request via create_callback.emit() This caused the same race condition and HTTP cancellation (~700-900ms) that we previously fixed in the "this_and_future" flow. ## Solution: - **Remove concurrent CREATE request** from frontend - **Use single UPDATE request** with "this_only" scope - **Backend handles both operations** atomically: 1. Add EXDATE to original series (exclude occurrence) 2. Create exception event with RECURRENCE-ID (user modifications) ## Implementation: - Frontend sends single request with occurrence_date and dragged times - Backend update_single_occurrence() already handled both operations - Added comprehensive RFC 5545 documentation for single occurrence modification - Cleaned up unused imports and variables ## Benefits: - No more HTTP request cancellation for single event modifications - Proper RFC 5545 EXDATE + RECURRENCE-ID exception handling - Atomic operations ensure data consistency - Matches the pattern used in this_and_future fix The "modify single event" drag operations now work reliably without network errors, completing the fix for all recurring event modification flows. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
