fix(menu): load pizza GLB at runtime when scene export has no mesh

Exported MenuScene.glb had cc0_-_pizza_salami with MeshRenderer but null
materials and no glTF mesh buffers (common when Unity imported an LFS pointer).
Add include/dishes standalone GLB and dishMeshFallback to GLTFLoader-inject
geometry when a dish root has no meshes. Track include/dishes outside Git LFS.
