chore(deploy): NO_PROXY defaults for downloaders; explain library root modes

- compose: app gets a default NO_PROXY (UMT_NO_PROXY) listing compose
  service names incl. qbittorrent / qbittorrent-nox / qb / transmission /
  deluge / aria2, so a proxy override never swallows downloader traffic.
- runbook: proxy and test-qB override templates use the same list.
- Settings: one-line hint on library root "管理方式" (managed vs
  register_only).

+compose 已给 app 设了缺省 `NO_PROXY`(`UMT_NO_PROXY` 可改),override 里重写 `NO_PROXY` 时别漏掉下载器的服务名。

 防火墙只放行 docker 网段:`ufw allow from 172.16.0.0/12 to 172.17.0.1 port 7891 proto tcp`。compose 默认网络已固定在 `UMT_SUBNET`(缺省 172.30.0.0/24,与本机其他网络冲突时在 `.env.deploy` 改成 172.16.0.0/12 内的空闲网段,如 172.16.80.0/24),否则 compose 自动分配的 192.168.x 网段不在放行范围内。Deno 的 fetch 会读 `HTTP(S)_PROXY`/`NO_PROXY`;TMDB、境外 Pi 上游、camofox 访问境外站都经此代理,站内(postgres/camofox)不走代理。
