- Implement real-time event filtering based on calendar visibility
- Add CSS styling matching external calendar checkboxes

Add intelligent caching and auto-refresh for external calendars 28b3946e86

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

Add immediate refresh when new external calendars are created 75d9149c76

When users add a new external calendar, events now appear instantly instead

Changes:
- Modified ExternalCalendarModal to return newly created calendar ID
- Enhanced on_success callback to immediately fetch events for new calendar
- Added proper visibility checking and error handling
- Removed unused imports to clean up compilation warnings

User experience improvement:
- Before: Add calendar → wait 5 minutes → see events
- After: Add calendar → events appear immediately

Fix Google Calendar UTC datetime format parsing 64c737c023

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.
