Audit 5.4 (t4:254/260): "Tus idiomas" and "Todos" eyebrows now sit
OUTSIDE any card at title-tier (20px) padding, styled with
eyebrowLabel -- were titleMedium w900 inside a PluriGlassSurface.
"Todos" also gains its missing total count ("{title} · {count}").
Audit 5.7 (t4:252): the header gained a real `search` action -- toggles
an inline TextField that filters the country list by name or ISO
code, not a decorative no-op button. New ARB key countriesSearchHint.
Item 5.6 (station count as a subtitle line, not a trailing widget) was
already fixed as an undocumented side effect of Tier3's row rebuild
(3303bd3) -- reconfirmed by direct read, no change needed here.
