feat: M2 HTTP/HTTPS 完善

- store: Local 增加 customDomains/subdomain/locations/hostHeaderRewrite/httpHeaders/basicAuth；Remote 增加 vhostHttpPort；migrate() 补列；CRUD 读写（JSOm 编解码）

- render: http/https proxy 输出 customDomains/subdomain/locations/hostHeaderRewrite/httpHeaders/basicAuth

- main: renderRemote 透传 M2 字段（customDomains 逗号拆分 splitCSV）

- web: LocalNode 折叠 HTTP 路由高级区；RemoteNode vhostHTTPPort；StatusView 显示 HTTP 访问端口

- 测试: TestRenderHTTPAdvanced / TestRenderHTTPSUsesCustomDomains；端到端 PUT canvas→config 验证通过
