统一 model3d 查看器状态类型命名：Model3DViewerStatus 改回 Model3dViewerStatus

- packages/model3d-viewer/src/status.ts：状态类型改名，与同文件的 Model3dViewerFailureReason / Model3dViewerStatusDetail 以及仓库既有 Model3d* 口径一致
- packages/model3d-viewer/src/Model3DViewer.tsx、packages/model3d-viewer/src/index.ts：跟随改名更新导入与引用
- src/components/image-editor/model3d-preview/Model3dViewerModal.tsx：跟随改名更新导入与状态类型引用

验证：npx tsc -p tsconfig.typecheck-guardrails.json --noEmit、npm run lint:eslint（改动文件）
