test(web-e2e): assert M3U movie metadata in the visible About block

The recognized-movie spec checked TMDB metadata with `.first()`, which
resolves to the hero copy. The shell mounts in watch state and its
collapsed hero turns `visibility: hidden` 300ms later, so the assertion
passed only when the routed TMDB lookup answered within that window.
Under parallel workers the lookup sometimes takes 300-500ms and the test
failed with "hidden".

The race predates the recent master commits: adb4889b0 fails the same
way, and a timing probe shows identical metadata/collapse timings there
and on b6357da6a. Scope the assertions to the watch-state About block,
the copy a watching user actually sees.
