Two design problems on the whole-page embed (pageEmbed) node:
- Double selection frame: the generic square cyan .ProseMirror-selectednode
outline stacked on top of the rounded .includeWrap border. Add node-pageEmbed
to the existing outline:none rule (already covering the transclusion nodes) so
only the single rounded border remains.
- Redundant 'open source' controls: the floating toolbar's external-link button
duplicated the header badge title link. Remove the toolbar button; the badge
title is now the single way to open the source (kept Refresh + ... menu).
Also swap the badge fallback icon IconArrowsMaximize (read as 'expand') for a
neutral IconFileText.
Follow-ups from review: render the badge whenever the source resolves (so the
only open-source link can't vanish when title+icon are empty), and label the
link (title/aria-label) + add the 'Open source page' i18n key (en-US, ru-RU).
