fix: 模型管理审查修复与归档

- 修复 registry 测试 ai mock 缺失 createProviderRegistry 导出
- 新增 POST /api/providers/test 支持未保存供应商配置连通性测试
- 供应商表单新增测试连接按钮，新建默认 openai-compatible
- 连通性测试按 ok 展示成功/失败，不再统一 success 样式
- 模型表单新建时也可测试供应商连接
- 模型页使用独立 provider 列表避免分页/搜索影响
- 移除模型管理组件内联 style
- 新增 ProviderTestResultResponse 共享响应类型
- 新增 bun run format:check 脚本
- 补充关键测试覆盖（删除关联、连通性、默认类型、表单测试）
- 更新 docs/user/usage.md、docs/development/*、design.md、tasks.md
- 归档 change 至 openspec/changes/archive/2026-05-29-add-model-management
