Restores the dimension reservation reverted in dae6f2d, scoped to
the embed.width && embed.height case only. No fallback aspect-ratio
when dims are null — that was the source of the dark letterbox bars
on Tenor/Klipy GIFs and OG-less images that triggered the revert.
The server-side probe in embedResolver.ts:196 already populates dims
for all image-type embeds; this change makes the client honor them.
