Upgrade i18next v26 + react-i18next v17 with SSR-safe init
Split initI18n() into separate server/client initialization paths
inspired by remix-i18next's architecture:

- initI18nServer(lng): no LanguageDetector, per-request language from
  Accept-Language header
- initI18nClient(): LanguageDetector reads <html lang> first to match
  server, then localStorage and navigator
- detectLanguage(request): parses Accept-Language for best match

Fixes rehydration errors caused by v26 removing initImmediate option
(replaced with initAsync) and LanguageDetector running on the server
where browser APIs don't exist.

Also makes <html lang> dynamic instead of hardcoded "en".
