- Add UID-based deduplication to prefer recurring events over single events with same UID
- Implement RRULE-generated instance detection to filter duplicate occurrences
- Add title normalization for case-insensitive matching and consolidation
- Fix external calendar refresh button with proper error handling and loading states
- Update context menu for external events to show only "View Event Details" option
- Add comprehensive multi-pass deduplication: UID → title consolidation → RRULE filtering
This resolves issues where Outlook calendars showed duplicate events with same UID
but different RRULE states (e.g., "Dragster Stand Up" appearing both as recurring
and single events).

Google Calendar ICS files use UTC datetime format ending with 'Z' (e.g., 20250817T140000Z)
which was failing to parse with DateTime::parse_from_str. Fixed by detecting 'Z' suffix,
parsing as naive datetime, and converting to UTC with and_utc().
Also cleaned up debug logging and unused variable warnings.

Implements server-side database caching with 5-minute refresh intervals to
dramatically improve external calendar performance while keeping data fresh.
Backend changes:
- New external_calendar_cache table with ICS data storage
- Smart cache logic: serves from cache if < 5min old, fetches fresh otherwise
- Cache repository methods for get/update/clear operations
- Migration script for cache table creation
Frontend changes:
- 5-minute auto-refresh interval for background updates
- Manual refresh button (🔄) for each external calendar
- Last updated timestamps showing when each calendar was refreshed
- Centralized refresh function with proper cleanup on logout
Performance improvements:
- Initial load: instant from cache vs slow external HTTP requests
- Background updates: fresh data without user waiting
- Reduced external API calls: only when cache is stale
- Scalable: handles multiple external calendars efficiently
