feat(files): 文件管理接入 Alist 存储(浏览、增删改、移动复制、上传下载、回收站)

- 文件管理根多出 st:<存储 id>(对照 MP 存储切换),Alist 媒体库目录照常出现在媒体库组
- 列目录一次 list,refresh 只在用户刷新时带;连不上返回 503 不当成空目录
- 新建目录 / 改名(同名不覆盖)/ 删除进 Alist 上的 .umt-trash 并可还原
- 存储内移动复制走 Alist API,本地 ↔ Alist 走整理同一套执行与账本
- 新增 PUT /files/upload(同名不覆盖,Alist 经服务端转传);下载 / 预览流式转发直链
