feat(launches): render the replay vehicle overlay from a store

The launches layer keeps the replay state, projection and wording and
presents the replay vehicle overlay through subscribeReplayOverlay(),
sending nothing for an unchanged frame, so the portable launches entry
stays free of Vue. The application shell publishes each presentation to
the gev-mission-replay store and the scene chrome teleports the vehicle,
orbit dot and callout into the globe container with the same markup,
classes, mode, transform, rotation and sonar opacities. Hiding keeps the
mode, place and text, as before.
