 * Reads the browser's preferred language and normalizes it to a supported

 * Walks `navigator.languages` (most preferred first), falling back to
 * `navigator.language`, and returns the first entry that maps to a supported
 * locale. Returns null when there is no navigator or none of the preferences
 * are supported, so callers can fall back to their injected default.
 * @returns {StaffbaseLocale | null} The preferred supported locale, or null.
