feat(world-overlay): render the visible map target list from a store

The world overlay presents its focusable mirror of painted cards through
subscribeWorldOverlayActions() and answers activateWorldOverlayAction();
the application shell publishes the list to a store and the scene chrome
renders the buttons and the status, announcing a repeated focus again.
The module stays free of Vue for the portable transit entry, and its
canvases remain painting surfaces.
