profile settings keyed (425 -> 352)

ProfileSettings reaches zero: api keys, profile, voice, dock, languages and the
model defaults.

Language names now come from Intl.DisplayNames rather than the catalog. The runtime
already knows "German" in English and "alemao" in Portuguese, so 28 names would have
been 56 hand-written entries that Intl gets right for free -- including for locales
not shipped yet. Same reasoning D7 gives for dates and numbers. The tag LIST stays
hardcoded: which languages you may claim to speak is a product choice.

ApiKeys had toLocaleDateString(undefined, ...), which followed the BROWSER locale --
the exact contradiction D7 describes. It uses useFormat().date now. Its revoked-key
toggle hand-rolled a plural with a ternary on n === 1; that is a real plural entry now.

Scanner: an Authorization header value like "Bearer <token>" is not a sentence.
Excluded by auth-scheme prefix; verified the delta is exactly the four such
credentials across both remaining areas.
