STAR-71: close search drawer when a result is clicked

The search drawer was only torn down as a side effect of a full page
reload. When a clicked result resolves to the page the user is already
on (same pathname, only the #hash differs), window.location.href does
not reload the page, so the drawer stayed open as an overlay while the
content silently scrolled behind it — making the result look
unclickable.

DrawerSearchResult now emits `closeDrawer` on click; Drawer forwards it
through the existing event chain to HeaderLayoutSearch.closeDrawer, so
the drawer closes on every navigation, reload or hash-only.
