implement contract cancellation feature and update contract statuses

- Added functionality to cancel contracts, allowing users to provide a reason for cancellation.
- Updated contract statuses to include SUSPENDED and changed CLOSED to COMPLETED.
- Enhanced the UI to reflect the new cancellation option and updated messaging for contract statuses.
- Refactored contract booking actions to accommodate changes in booking logic for ONE_TIME and GENERAL contracts.
- Removed clearance document management from the contract detail page, as it is now handled per booking.
- Introduced a SQL script to reset bookings and train schedules for development purposes.
