Fall through to the post page when a reel embeds only its cover frame
CI / Typecheck, test, build (pull_request) Successful in 29s

The captioned embed stopped shipping a reel's video_url and never draws a
logged-out <video>, so both the payload and the DOM hand back the cover
frame alone. Because that still counts as media, the post-page fallback
never fired and a reel resolved to a still image.

Trigger the fallback when the URL is a reel (or the payload declared a
video) but no video was found, so it reaches the post page, whose payload
still carries the progressive file in video_versions. The embed's
caption, handle and avatar are carried forward, since the post-page
payload does not include the owner.
