feat: показывать версию приложения в настройках, версия 1.1.0

Версии бэкенда и фронтенда были не синхронизированы и нигде не отображались
в интерфейсе — непонятно было, обновилось ли приложение после пересборки.
Теперь единая версия 1.1.0 приходит с бэкенда через /api/health и мелким
текстом выводится внизу страницы настроек.
