fix(upload): 修复文档上传多文件失效与 401 跳登录

- 上传改走 axios 复用 401 自动刷新，显式 multipart/form-data 修复 MultipartException
- DocUpload 文件 Tab 加 multiple，上传 handler 按 TDesign requestMethod 契约重写
- AuthController 的 refresh cookie Secure 属性按请求 scheme 动态判断，HTTP 自动降级
- application.yml / application-dev.yml 统一 refresh-cookie-secure 配置
