UX: Avoid header topic-info flicker when using ?page= params (#28117)
In this case, there is no 'nearPost' param in the URL. Instead, the server preloads a post-stream with whichever page of posts is requested. We can check for that situation using `postStream.firstPostPresent`.

Also updates the widget-header version to fetch a value from the service on initial render, instead of relying on the observer triggering.
