refactor: remove gate pass granting logic from clearance services and UI

- Removed the gate pass granting functionality from the BookingClearanceService and ContractClearanceService, replacing it with a new method to retrieve gate pass status from train schedules.
- Updated the ContractsController to eliminate endpoints related to gate pass granting.
- Refactored the UI components (ExportClearanceStepper and PhasedClearanceActionPanel) to reflect the new gate pass securing process, linking to the train scheduling interface instead.
- Cleaned up related constants and query hooks, removing unused code and references to the gate pass functionality.
- Adjusted types in the contracts to accommodate changes in the gate pass handling logic.
