Theseus 0.3.62: picker says just "English", not "American English"

Intl.DisplayNames.of("en-US") returns "American English", which spells out a
distinction the picker doesn't make — one row per language, with English the
UK original. Pass the base code to Intl so the chip tooltip, the "Automatic
(…)" label and the Settings hint all read as the plain language name
(English, Russian, Portuguese, Chinese) regardless of which regional variant
the OS or the saved setting happens to be.
