Client: Eliminate some redundant buffer writes

Huh, this doesn't make any sense at all... The scenewide uniform data needs to be updated once per frame, not once per mesh. Perhaps this was supposed to be per-material or even per-mesh data, but I think it's just a copy/paste error.

Caught this thanks to tracing WebGPU API calls, so etrace already paid off... This is wasteful and can safely be removed.
