I noticed that some of these are missing for full support of this translation. Please let me know if initial support is sufficient

• An entry in LocaleUtils

  "pt-BR": {
    code: "pt-BR",
    description: "Português (Brasil)"
  }

• A flag pt-BR.png in web/client/components/I18N/images/flags
• And the translations missing in pt-BR missing-pt-BR-translations.txt
