fix: pass all scene data through mapInputProps to Remotion

mapInputProps() was cherry-picking only 6 fields per scene, dropping
sceneType, code, list, comparison, mockup, and wordTimestamps. This
caused SceneRouter to fall through to the generic Scene component for
every scene, making all videos look like plain word overlays.

Fix: spread the full scene object (...s) instead of cherry-picking.
Added missing fields to RenderInput type: sceneType, code, list,
comparison, mockup, wordTimestamps.
