World tint: include props/ materials; log static studio draws

Static props commonly use brush-style props/... materials
(props/woodcrate001a is LightmappedGeneric), so the models/props-only filter
missed them. Include the props/ prefix.

Also log the first static prop studio draws and a 500-draw summary so we can
see whether the engine draws props through DrawModelStaticProp at all.
