Refactor wagon type handling and container wagon calculations

- Removed maxWagonsPerTrain from WagonType entity and related DTOs.
- Updated containerWagonsForLines function to calculate required wagons based on container lines more accurately.
- Added unit tests for containerWagonsForLines to ensure correct calculations.
- Adjusted related services and scripts to reflect the removal of maxWagonsPerTrain.
- Enhanced booking and contract components to use new status labels for better user experience.
- Implemented validation for unique container numbers in shipment forms.
