- 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.
