Subject: [PATCH] refactor(i18n): simplify locale resolution and clean up code

Simplify the locale resolution logic in the request utility by directly using stored locale with default fallback, remove the unused getNavigatorLanguages function, and streamline the initial locale setup in the i18n entrypoint while persisting the default locale when no stored locale is present.
