feat(i18n): add country name translations for article country badges

Move COUNTRY_LABELS to i18n.py (shared). Add get_country_name(country_str, lang)
that maps English DB values (e.g. "Germany") to localised names via existing
dir_country_* translation keys. Register as Jinja filter country_name.
Apply to market_results.html country badge.
