feat(app): новый визуальный язык, верхняя навигация, портфели, создание счетов и ручные события

Тема и общие виджеты (AssetIcon, ServiceMark, HelpTip, глоссарий), верхняя панель TopNav и вкладки Аналитики вместо NavSidebar, иконки PWA. Экраны: портфели, создание брокерского счёта, ручное событие, правка инструмента, Обзор карточками по скоупам и таблица активов, пересчёт метрик с опросом /metrics/status. design-system.md обновлён.
