- 新增 log_datasource.go / log_proxy.go / user_api_token.go 后端控制器
- 新增 log_datasource.go model
- 新增 monitor/log-center.ts API 模块
- 新增 LogCenter 前端组件及页面
- 重构 deployment 相关组件 (HPDA/UpdateImageModal/bundle-yaml 等)
- 新增 ResetPasswordDialog / code-snippet-block / copy-button 等 UI 组件
- 重构多个 k8s 相关组件 (TopologyView/ResourceVisualEditor/PodFileBrowser 等)
- 更新多个 API 和工具函数 (auth.ts/monitor/index.ts/request.ts 等)
