Implement calendar display with multi-day event support

- Added timezone support (Pacific/Auckland) for calendar events
- Implemented recurring event handling using recurring_ical_events library
- Created horizontal 5-day column layout for calendar display
- Fixed multi-day event rendering to show events across all active days
- Updated calendar to show next 5 days (today + 4)
- Reduced font sizes and padding for compact display
- Changed image rotation interval to 60 seconds
- Added pytz and recurring_ical_events dependencies
