[Enhancement]: Add missing strings to translate

[thehijacker]

Describe the Feature/Enhancement

Testing on iOS. Even if I can not select Slovenian language in menu, the GUI was in Slovenian. It looks like it checks in what languages is the iOS. So I was able to check everything and noticed lot of missing untranslated strings, even if in weblate my translation is on 100 %.

Why would this be helpful?

To add fixed English strings as variabled so they can be translatable.
