feat(runtime-control): 注册流程改为通过AuthZ服务

注册现在通过AuthZ进行处理，而登录/运行时查找仍然使用deploy-control。
更新了API调用逻辑，将注册请求从直接调用deploy-control和instance-api
改为统一调用AuthZ服务。

- 修改了注册API路由(/api/runtime/register)以使用callAuthzService
- 更新README.md文档说明新的架构流程
- 添加AUTHZ_API_BASE_URL环境变量配置
- 更新注册页面描述信息
- 移除了不再使用的callDeployControl和callInstanceApi相关代码
