Subject: [PATCH 1/2] fix(i18n): correct Irish locale flag and language label

- Fix locale key in lang-list.json from "locale-ie-GA" to "locale-ga-IE"
  to match the actual locale code used in IntlProvider
- Add ga -> ie mapping in getFlagCodeForLocale() so the Ireland flag is
  shown instead of the Gabon flag
- Add missing ["ga", "ga-IE"] entry to check-locales.cjs validation list

Fixes NginxProxyManager/nginx-proxy-manager#5354

Subject: [PATCH 2/2] test(i18n): add tests for getFlagCodeForLocale flag
 mapping

Cover standard locales, all special-case mappings (ja, zh, vi, ko, cs,
ga), and the undefined/fallback path to prevent future flag regressions.
