Translates the 16-language locale_names block in zh-CN, zh-TW, ko, hi,
vi, tr, de, fr, es, pt-BR, ru, uk, it, pl to the target locale's own
language (e.g. de file: 'en' => 'Englisch', 'ja' => 'Japanisch').
DocumentEditor blade no longer hardcodes 'en' as the locale_names
lookup — falls back to the current UI locale. Test still passes
because tests run with default app locale 'en' and the en file
maps to "Japanese" / "English" etc.
A user editing in ja now sees [English] [日本語 ★] tabs instead of
[English] [Japanese ★].
