The level had zero actors besides the ship, so it rendered fully
black (no directional light, no sky light). Added a DirectionalLight
and a real-time-capture SkyLight so the placeholder ship is actually
visible during PIE testing.
BP_ShipPawn: cone mesh, FloatingPawnMovement for gravity-free flight,
spring-arm chase camera. Placed in L_TestFlight and set to
auto-possess Player 0 for PIE testing. No input wiring yet.
