Stack breadcrumb above page title (Angular parity)

Angular renders the breadcrumb trail on its own row above the H1 title.
React had them in the same flex row with justify-content:space-between,
which squeezed the breadcrumb column and forced 'Главная / Онлайн-Табло'
to wrap onto two lines. Switch the header-right container to column
layout so breadcrumbs and title stack vertically regardless of width.
