Function constructSerializedUrl

packages/angular/ssr/src/utils/ng.ts:211–229

* Constructs a normalized and serialized URL string from its components. * * This function uses the provided `Router` instance to parse and serialize the URL, * ensuring that the resulting string is consistent with the router's configuration. * It also handles the optional `prefix` parameter to

(
  router: Router,
  url: { pathname: string; search: string; hash: string },
  prefix?: string | null,
)

 * This is important for the URL to be correctly parsed and serialized by the router as it might have different encodings.
