Internalisation: grouping ticket

[PascalinDe]

This ticket is to group smaller tickets related to internalisation:

• create necessary tickets (see discussion below)
• Internalisation: initial language is not set properly #328
• Internalisation: follow data format from the backend #329

[PascalinDe]

in my opinion, the first thing to address is that the backend (and sometimes the frontend as well) handles form titles in the form of an object

{en: 'english title', de: 'german title', fr: 'french title'}

that gets than transformed into flat strings Title, TitleDe and TitleFr (same with other objects), the code on the frontend's side should be adapted so that it continues to handle the object is it is send from the backend, since that easily allows for adding/removing languages

Even better, use a Map. So you don't need to have Objects.entries(titles) if you want to use an iterator.

grouping tickets are not working well for this project, I'll close this one
