- Added ContainerValidationService to handle 20ft weight-pairing logic. - Introduced validate20ftWeightPairing utility function to check weight differences. - Updated BookingPricingService to include overweight line details and pairing errors in price response. - Enhanced BookingTransitionService to reject submissions with unpairable 20ft containers. - Created ShipmentValidation interface for pre-submit validation of container contracts. - Integrated shipment validation into the contract booking process, providing warnings for overweight containers and hard blocks for pairing errors. - Updated front-end components to display validation results and prevent submission when errors are present.
