i18n: tighten typings for payloads and translator interfaces

- Export typed I18n payload aliases for ICU params
- Replace inferred translate/locale exports with generic i18n type refs
- Parameterize i18n_conf and i18n_conf_icu with payload generics
- Drop unused LanguageConfig and default LIB_CONFIG instance
