feat(train-scheduling): implement container movement between wagons

- Added functionality to move containers between wagons in the train scheduling system.
- Introduced  API endpoint and service method to handle container movement.
- Updated  component to support drag-and-drop for rearranging containers.
- Enhanced  to allow moving containers to other wagons via a context menu.
- Implemented UI feedback for container movement actions, including loading states and success/error notifications.
- Updated relevant types and constants to accommodate new container movement logic.
- Added tests for the rule engine to ensure proper handling of hazardous bookings.
