Replace broad Contains("light") with IsTimelineControlledLight() that matches
only objects actually controlled by timeline handlers (blinklight, spotlight3d,
_wash_, laser). Neonsigns, glow meshes, UV scroll objects and other static stage
props now keep their prefab default state instead of being silently disabled.
Also fix UVScrollLight handler to use GetComponentsInChildren<Renderer>(true)
so inactive renderers are included in material search.
