Adds a loading spinner to the message history overlay,
improving the user experience by providing visual feedback while the
message edit history is loading.
We redesign the message history modal to make it look similar to the
drafts and scheduled messages, using the shared styling/rendering
logic for that those existing elements to have a less goofy widget.
Fixes#28695.
postcss-preset-env transpiles this back as necessary. (It does a
better job than we did, in fact: we had several four-argument hsl()
calls that should have been hsla().)

Ever since we started bundling the app with webpack, there’s been less
and less overlap between our ‘static’ directory (files belonging to
the frontend app) and Django’s interpretation of the ‘static’
directory (files served directly to the web).
Split the app out to its own ‘web’ directory outside of ‘static’, and
remove all the custom collectstatic --ignore rules. This makes it
much clearer what’s actually being served to the web, and what’s being
bundled by webpack. It also shrinks the release tarball by 3%.
