fix: complete the gallery quality pass — turntable regression, three old-era restages (#65)

* fix: pin turntable still to a readable three-quarter Suzanne pose (regression from #62)

* fix: restage gn-sdf-remesh to the gallery visual style (incorrect PASS in #62)

* fix: restage bmesh-gear so the steel material its script specifies actually renders (incorrect PASS in #62)

* fix: deepen depsgraph-export base-cube contrast and tighten framing
