Voucher number visible in the app

This is a temporary solution. The purpose is that the employee can list the receipt number and then when weighing, this receipt number can be placed. In an expense report or invoice this can then easily be found together. Later the intention is to also make ''Weighings'' visible in the app and that you can make a weighing from within the app. Just like in the backend and in the app just like the rental option.

Idea to build it in as a feature flag? May be in the work order behind the text ''Work order''.
