feat(portal-shell): integrate next-intl + merge messages from teacher-portal (P1-4)

xiner/Edu

- Add next-intl v4.13.2 with cookie-based locale (no i18n routing)
- Create src/i18n/request.ts reading NEXT_LOCALE cookie
- Merge zh-CN/en messages from teacher-portal + add shell.dev.templates namespace
- Wrap next.config.js with withNextIntl plugin (Turbopack resolveAlias)
- Refactor RootLayout to async + NextIntlClientProvider + getLocale/getMessages
- Replace ThemeI18nProvider with ThemeProvider (theme-only, i18n removed)
- Remove locale/setLocale from PluginStore
- Rework locale-switcher to useLocale/useTranslations + router.refresh
- Update dev/templates page to use getTranslations (Server Component)
- Fix WorkbenchPageShell test (loading prop + center instead of children)

Verified: locale switch via NEXT_LOCALE cookie changes <html lang> and messages
zh-CN: 保存/取消/切换侧栏 | en: Save/Cancel/Toggle sidebar
