- Unify logic for loading editor/property/doc/extractable translations. - Replace legacy `TranslationServer` methods with translation domains for internal translations. - Only pre-create editor/property/doc translation domains in editor builds. - Prevent adding `null` translation. - Fixes potential loading of duplicated editor translations. - Add internal `has_translation_for_locale()` instead of calling `get_loaded_translations().has()`.
