Implement logout functionality for account page

- Create LogoutButton client component using signOut from next-auth/react
- Update account page to use LogoutButton instead of static link
- Convert account page to async server component for proper i18n
- Add locale-aware routing for settings link
- Add logging-out-message translations (EN/HR)
