feat(ux): dark/light theme + en/ja i18n + user preferences

UX全体にテーマと言語設定を追加。

- lib/db/migrations/004_user_prefs.sql: users に theme/locale 列を追加(既定 dark/en)
- lib/i18n/: dictionary(en/ja) + I18nProvider(クライアントcontext: locale/theme/t/setLocale/setTheme) + server.ts(SSR用 getLocale/getTheme/translate) + constants.ts
- app/layout.tsx: theme/locale Cookie を読み <html class/lang> をSSR、I18nProvider でラップ(フラッシュなし)
- tailwind darkMode:'class' + 全画面に dark: バリアントを一括付与(Nodeスクリプト lookbehind で安全に変換)
- components/layout/ThemeToggle: 即時クラス切替+Cookie+永続化
- app/profile: テーマ/言語セレクタ、chrome翻訳(Header/ProjectNav/login/dashboard/profile)
- PATCH /api/users/me: theme/locale を受理(バリデーション→400)、Cookieを設定
- E2E: locale=ja storageState で既存JAアサーションを維持、theme-i18n.spec で既定en/darkと切替を検証
