docs(ops): 统一 md.tkmind.cn 域名与 105→103 反代拓扑

将管理后台公网域名从 gadm 更正为 md.tkmind.cn，补充 105 nginx 反代 103 的部署说明，
默认 VITE_BASE_PATH=/ 以支持 /analytics/seo-geo 根路径访问。

+#   Admin API: 127.0.0.1:8085
+#   vite preview: 127.0.0.1:5174（根路径 base=/）
+#
+# 前端 fetch 使用根路径 /auth、/admin-api、/api；nginx 需单独反代到 Admin API。
