These pages are desktop-enabled (they get the DesktopHeader via the /profile
allowlist) but had no desktop layout, so their content stretched edge-to-edge on
wide screens. Add a centered max-width container + a desktop title to the main
profile sub-pages (bookmarks, following, orders, settings, wallet, addresses,
sets). Grids use a wider max-width; single-column lists a narrower one.
ProfilePagesHeader is already lg:hidden, so the mobile header still disappears.
