Enhance scheduling and drag-and-drop functionality in the Calendar component

- Improved drag-and-drop experience for event scheduling with visual feedback and better cursor styles.
- Added state management for tracking repetitions, including locked schedules and currently scheduling repetitions.
- Implemented re-staggering logic to prevent overlap of scheduled events.
- Enhanced event generation to include time points for soaking, airdrying, and cracking phases.
- Updated the calendar to preserve and restore scroll position during event updates.
- Refactored event handling to ensure smooth interaction and improved user experience.
