fix(config): add embed.html to tailwind content config

This fixes a layout issue in the embed player where the body height would collapse to the default video height (150px) because `h-screen` and other utility classes were missing from the generated CSS. Adding `embed.html` to `tailwind.config.cjs` ensures these classes are generated.
