refactor: remove 3D code from GenerateImageNode and nanoBananaExecutor

- Remove text-to-3d/image-to-3d from IMAGE_CAPABILITIES
- Remove is3D memo and conditional handle/label styling
- Remove 3D output preview block
- Remove output3dUrl from model change handlers
- Remove is3DModel detection and mediaType from nanoBanana executor
- Remove 3D response handling from nanoBanana executor
- Remove output3dUrl from NanoBananaNodeData and its defaults
- Remove 3D fallback from nanoBanana in connectedInputs
