The bundled ceiling-fan model.glb was stale (no animation clip, two slots).
Replace it with the variant matching production storage: an `On` animation
clip and a third `slot_base` paint slot. Same dimensions/offset, so no catalog
metadata change.

Replace 89 bundled item model.glb files with the authored/optimized
versions currently served from prod storage (items/system/<slug>/model.glb),
so the committed source of truth matches what live projects load and a
catalog re-seed no longer clobbers authored geometry. Items with no prod
object (404) are left as-is.
