Refactor calendar datasource and event management

Enhances calendar flexibility by introducing group-based column spanning and improving cross-mode event handling

Adds support for:
- Dynamic column grouping in date and resource modes
- Consistent event drag-and-drop across different calendar views
- More robust all-day event layout calculations

Improves event management logic to handle resource and date mode transitions more elegantly
