Store picker in topbar, redesign cabinet, rename to WBfeed.ru

- index.html: store dropdown in topbar (switch without leaving page)
- cabinet.html: store-cards with Активировать/Проверить, edit hidden in <details>
- Removed 'Используется' button, active shown as green card + label
- next=index param to return to main page after store switch
- Brand name changed to WBfeed.ru across all templates
