- routing: localeDetection:false — a non-prefixed URL always serves fa (default);
English only via explicit /en/ prefix. Browser Accept-Language no longer
redirects fa pages to /en on every click.
- AdminShell + DashboardSidebarNav: use next-intl Link + usePathname (from
@/i18n/navigation) instead of plain next/link, so links preserve the current
locale and active-state matches the prefix-stripped path.
