suppress world interaction while a menu panel is open

DialogueInteractable, DialogueTransitionController, and DialogueUIVisibility are
reworked against the new UI layer: visibility is driven by UIStateController
rather than each component toggling canvases itself, which removes the
duplicated show/hide logic the two had accumulated.

NPCStandIn now ignores the interact button while UIStateController reports a
menu open, so pressing interact through an open panel no longer starts a
conversation behind it.

The yarnproject change is graph-editor node positions only.
