fix: enhance schedule overlap validation in OrderSchema

- Added logic to retrieve existing schedule dates for a given schedule ID to improve overlap detection.
- Updated the conditions for checking schedule overlaps to include participant IDs, day of the week, and time slots, ensuring more accurate validation.
- This change aims to enhance the integrity of scheduling operations and provide better feedback for users regarding scheduling conflicts.
