/**
 * Bridges messaging header content from inside <MessagingApp> into the
 * portal shell's <ScreenHeader>. Render this as a child of <MessagingApp>
 * with `hideTopBar` set, and the messaging UI's own <MessagesTopBar /> is
 * suppressed in favour of populating the existing portal header.
 *
 * Right-hand actions are delegated to <MessagesHeaderActions /> from
 * messaging-ui so this stays in sync with <MessagesTopBar />. The breadcrumbs
 * are owned here because the portal shell shows them differently from the
 * messaging-ui's inline page-title fallback.
