fix(web): search results panel spans full content width

The header search overlay was anchored to the search bar's width, leaving a
dead strip on the right where scrolling hit the background page. Anchor it to
the sticky #mobile-header instead (which already sits right of the sidebar), so
it spans the full main-content width — sidebar stays visible, no dead strip.
