Royal Mail Integration – Updated the tracking translation for events EVKLS and EVKLC

The Royal Mail tracking events EVKLS and EVKLC pertain to delivery to a collection point for collection, not to the final delivery. To accurately reflect this, the tracking events EVKLS and EVKLC have been remapped to indicate "Ready for Collection," rather than treating them as "Delivered" events. This ensures that the correct tracking information is sent to customers.
