docs(storybook): tidy SW Home Menu page and hide the Viewer comparison

Home Menu: the recent-files sub panel loses its title / Figma node caption and its
frame fits the open panel (+16px) instead of a fixed 860px; the Integration
(property window / SWPopup / Escape) section leaves the page and stays in the
hidden home-menu-integration Story.
SW Viewer: SWHeader vs Viewer Header is tagged verification (ID and URL kept for
the browser tests); inventory and README updated.
