fix(web): unify ReUI chrome and stop tab underline overlap

Секции страниц переведены на segmented Tabs (c-tabs-9), статус грида — ToggleGroup в toolbar. Убраны календарь задач, пустые вкладки мониторинга и demo-деревья ReUI. KPI overflow как в CFDM, DetailPanel на карточке модуля, один FrameSection.
