This commit resolves the "Failed to fetch" errors when updating recurring
event series through drag operations by implementing proper request
sequencing and fixing time parameter handling.
Key fixes:
- Eliminate HTTP request cancellation by sequencing operations properly
- Add global mutex to prevent CalDAV HTTP race conditions
- Implement complete RFC 5545-compliant series splitting for "this_and_future"
- Fix frontend to pass dragged times instead of original times
- Add comprehensive error handling and request timing logs
- Backend now handles both UPDATE (add UNTIL) and CREATE (new series) in single request
Technical changes:
- Frontend: Remove concurrent CREATE request, pass dragged times to backend
- Backend: Implement full this_and_future logic with sequential operations
- CalDAV: Add mutex serialization and detailed error tracking
- Series: Create new series with occurrence date + dragged times

This commit resolves the 404 error when dragging/updating non-recurring events.
The issue was in the regular event update handler where it was generating fake
event hrefs based on the UID (format: "{uid}.ics") instead of using the actual
href returned by the CalDAV server during event fetching.
Changes:
- Use event.href from the stored event data instead of generating fake hrefs
- Add comprehensive debug logging to track event updates
- Fallback to generated href only when the stored href is missing
Debug logging added:
- "🔍 Found event {uid} with href: {href}" - shows which href is being used
- "📝 Updating event {uid} at calendar_path: {path}, event_href: {href}" - tracks update parameters
- "✅ Successfully updated event {uid}" - confirms successful CalDAV updates
This matches the fix previously applied to the deletion functionality and ensures
that CalDAV PUT requests target the correct resource URLs.

This commit resolves multiple issues with event deletion:
Backend fixes:
- Fix CalDAV URL construction for DELETE requests (missing slash separator)
- Improve event lookup by href with exact matching and fallback to UID extraction
- Add support for both RFC3339 and simple YYYY-MM-DD date formats in occurrence parsing
- Implement proper logic to distinguish recurring vs non-recurring events in delete_this action
- For non-recurring events: delete entire event from CalDAV server
- For recurring events: add EXDATE to exclude specific occurrences
- Add comprehensive debug logging for troubleshooting deletion issues
Frontend fixes:
- Update callback signatures to support series endpoint parameters (7-parameter tuples)
- Add update_series method to CalendarService for series-specific operations
- Route single occurrence modifications through series endpoint with proper scoping
- Fix all component prop definitions to use new callback signature
- Update all emit calls to pass correct number of parameters
The deletion process now works correctly:
- Single events are completely removed from the calendar
- Recurring event occurrences are properly excluded via EXDATE
- Debug logging helps identify and resolve CalDAV communication issues

- 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

- When dragging recurring events, preserve original series start date
- Only update time components, not date, to prevent series from shifting days
- For timed events: use original date with new start/end times from drag
- For all-day events: preserve original date and duration pattern
- Added debug logging to track date preservation behavior
- Maintains event duration for both timed and all-day recurring events
Fixes issue where dragging a recurring event would change the date
for all occurrences instead of just updating the time.
