enable_language

Add a language to the model so it can be translated into. The language then appears in the model's language settings and becomes a valid target for translate_elements.

Do this first — translating into a language the model doesn't yet offer is refused rather than silently accepted, so that translations can't pile up invisibly against a language nobody can see. Enabling a language does not change the model's default language and does not translate anything by itself.
