- Add new standard view types: 30day, 60day, 90day, 365day
- Add 3day view as standard option
- Add custom day range input (1-365 days) in context menu
- Update PillTabGroup to show labels when no icon is provided
- Change MultiDayView dayCount prop from union to number type
- Add ultra-compact class for views with 14+ days
