Enhance FalukantService and UI components for improved product handling

- Updated FalukantService to allow optional inclusion of productType in queries, enhancing flexibility in data retrieval.
- Modified SaleSection.vue to conditionally display product information and size, improving user experience by handling cases with no product.
- Added new German translation for 'runningNoProduct' to enhance localization support for users.
