Merge branch 'master' into mici-sla-ui

OnroadViewContainerSP nests a vertical scroller between the outer horizontal
scroller and road_view/info_panel. Stock click suppression relies on a child's
_touch_valid_callback being gated by its parent scroll panel — with the
container in the middle, children were only gated by the inner panel, so an
outer L→R drag never invalidated their touch and the click fired on release
(immediately popping to home).

- Chain children's touch_valid through the container's own touch_valid so
  outer-scroll state propagates to nested children.
- Add OnroadInfoPanel._handle_mouse_release mirroring AugmentedRoadView's
  bookmark guard, so an R→L bookmark drag on the info panel doesn't fire the
  click on release.
