Enhance SaleSection component to group and display transport data

- Updated SaleSection.vue to group running transports by relevant attributes, improving data organization and readability.
- Added a new computed property to calculate vehicle counts and total quantities for grouped transports.
- Introduced a new column in the UI to display the count of vehicles associated with each transport group.
- Updated German localization file to include translation for 'runningVehicleCount', enhancing user experience for German-speaking users.
