Implementa infraestrutura de i18n com suporte inicial a English e
Português (Brasil). Seletor de idioma em Settings > System > Preferences.

- Instala react-i18next e i18next
- Cria arquivos de tradução (en, pt-BR) para common, home, settings, layout
- Traduz layout (sidebar, header, footer), home e settings/system
- Persiste idioma via localStorage + KVStore (ui.language)
- Seletor de idioma na página Settings/System
