Links prefetching (#225)

1. Marketing Layout: speed up rendering by retrieving user session from cookies instead of using server side request
2. Use "redirecting" state when signing in to keep displaying a loading state while Next.js redirects to home page
3. Use "useCallback" to prevent double tracking when switching pages
4. Add links pre-fetching in marketing navigation
5. Add new pending state to MFA verification form
6. Pre-fetch sign-in/sign-up pages
7. Fix i18n when using regional languages
8. currency formatter should default to the region if it exists
9. Update packages
