Language preference

[aapeliv]

Right now there is some black magic that figures out what language to show you the UI in. We forgot if it's possible and/or how to force this... We should have this easy and obvious to configure in the frontend.

• There should be a language selection toggle (also it should link to "Help translate Couchers to your language" or similar) that stores the value in a cookie called couchers-preferred-language and changes the language based on this, this should also send the info to the backend to be stored in the profile once that is implemented

• The frontend should have automatic language detection code and suggest switching languages in e.g. a snackbar (but if you dismiss it it should remember you did and not annoy you in the future), or maybe highlight the language toggle when the UI language doesn't match, or similar

• The user's language preference should be stored in the backend in the profile field

• The backend should set the language preference in a cookie to overwrite the frontend when a user logs in
