Connor Johnstone 1b57adab98 Implement complete recurring event deletion with EXDATE and RRULE UNTIL support
Frontend Changes:
- Add DeleteAction enum with DeleteThis, DeleteFollowing, DeleteSeries options
- Update EventContextMenu to show different delete options for recurring events
- Add exception_dates field to CalendarEvent struct
- Fix occurrence generation to respect EXDATE exclusions
- Add comprehensive RRULE parsing with UNTIL date support
- Fix UNTIL date parsing to handle backend format (YYYYMMDDTHHMMSSZ)
- Enhanced debugging for RRULE processing and occurrence generation

Backend Changes:
- Add exception_dates field to CalendarEvent struct with EXDATE parsing/generation
- Implement update_event method for CalDAV client
- Add fetch_event_by_href helper function
- Update DeleteEventRequest model with delete_action and occurrence_date fields
- Implement proper delete_this logic with EXDATE addition
- Implement delete_following logic with RRULE UNTIL modification
- Add comprehensive logging for delete operations

CalDAV Integration:
- Proper EXDATE generation in iCal format for excluded occurrences
- RRULE modification with UNTIL clause for partial series deletion
- Event updating via CalDAV PUT operations
- Full iCal RFC 5545 compliance for recurring event modifications
