feat(k8s): M3 Pod文件上传 + ExecInPod WebSocket协议重写

M3: Pod 文件上传
- 后端: POST .../pods/:pod/files/upload (multipart, base64分块exec写入)
- 前端: PodFileBrowser 增加上传按钮 + FormData API
- 路由: 新增 Kuboard (:clusterCode) + 旧 (:id) 两套路由

重大修复: ExecInPod 从 raw HTTP SPDY 改为 WebSocket channel.k8s.io
- 旧方案: HTTP POST + SPDY upgrade → 无法解析响应（协议头缺失 + 帧解析复杂）
- 新方案: gorilla/websocket Dialer + channel.k8s.io 子协议 → 和 ExecTerminal 一致
- 影响: 文件浏览/下载/上传全部恢复正常

修复: BusyBox ls 解析
- BusyBox 不支持 --time-style 参数，默认输出 Mon DD HH:MM 格式
- 解析器改为自动检测 GNU vs BusyBox 日期格式

 **目标**: PodFileBrowser 增加上传能力
 
 **改动**:
-- 后端新增 `POST .../pods/:pod/files/upload` — 用 exec tar 解包写入
-- 前端 PodFileBrowser 增加上传按钮 + 拖拽上传
+- 后端新增 `POST .../pods/:pod/files/upload` — multipart 表单接收，base64 分块 exec 写入
+- 前端 PodFileBrowser 增加上传按钮 + FormData 上传
+- **重大修复**: `ExecInPod` 从 raw HTTP SPDY（不工作）改为 WebSocket channel.k8s.io 协议（和 ExecTerminal 一致）
+- **修复**: BusyBox `ls` 不支持 `--time-style`，解析器改为兼容 BusyBox 默认日期格式
 
 **验收标准**:
-- [ ] 可上传文件到 Pod 容器内
-- [ ] 上传后文件列表刷新可见
+- [x] 可上传文件到 Pod 容器内
+- [x] 上传后文件列表刷新可见
+- [x] verify 字段返回正确文件大小
