Fix image peek in carousels for quote posts

Plumbs `isWithinQuote` from `ImageEmbed` through to `Gallery` and uses
it to render the carousel with a smaller per-breakpoint height + square
crop. Drops the `FeedEmbedRecordWithMedia` derivation, which has been
dead since the chat-message squashing change removed every site that
set that enum.

Closes APP-2098
