Refactor event rendering with column-based event management

Improves event rendering by integrating event filtering directly into column data sources

Key changes:
- Moves event filtering responsibility to IColumnDataSource
- Simplifies event rendering pipeline by pre-filtering events per column
- Supports both date and resource-based calendar modes
- Enhances drag and drop event update mechanism

Optimizes calendar rendering performance and flexibility
