fix: a new view opens at its top instead of the last view's scroll offset
The router had no scrollBehavior, so Settings entered from a scrolled feed
opened scrolled too, its heading and tab strip under the nav. Back/forward
restores the saved position, and a new query on the same view keeps its
place.
