feat: 管理后台迁移至 FastAPI + Jinja2 服务端渲染
- GET /admin：Jinja 模板渲染（登录页 / 管理台），媒体库、播放列表、设置由服务端渲染 - POST /admin/login：表单登录 + HMAC 签名 Cookie（DPM_ADMIN_SECRET），GET /admin/logout 退出 - /static/admin.css + admin.js：动态操作（上传进度/播放控制/设置/SSE 状态/预览弹窗）调 REST 后整页刷新 - 前端移除 React Admin 页面与 /admin 路由（Admin.jsx 删除）；媒体/播放列表接口保持不变 - 依赖改用 uv 管理（pyproject.toml + uv.lock，含 jinja2），README 更新启动方式
