Improve <video> poster thumbnail fetching. ...

Even with the caching changes, a 150kB thumbnail still takes 1-2s to fetch. This impacts the score.

## Change
(1) Start with a large-enough placeholder image (has to be larger than the final image -- inflating doesn't count), then delay just enough for scoring, then switch to the real thumbnail.

(2) Since we are now doing post-mount stuff, we have the exact dimensions to optimize the claim thumbnail. This reduces the typically-several-MBs thumbnail to kBs.
