Add a "Lanes" section under Account that reuses LanePicker inline, completing
the round trip with Boundaries. Refactor LanePicker to support an `inline`
variant (bare panel vs modal) and apply changes immediately on toggle — so the
account panel needs no explicit save and the home modal now previews the nav
rail live as you pick. Selection still persists through the shared prefs store.
