feat(nav): client area tabs in main navigation

- Add Cabinet button to header (dashboard icon)
- When in /clientarea/* show tabs instead of search input
- Tabs: Заказы | Предложения (SELLER only) | Адреса | Профиль | Команда
- Hide Explore/Quote toggle in client area
- Remove SubNavigation for clientarea (tabs moved to MainNavigation)
