Do not cache user public files as immutable

[remorses]

The Remix build.assetsBuildDirectory is build/client, this folder contains user public files. The serve code is caching these files as immutable which means that even if the user changes the content of a file but not the name the file it will not be revalidated.

This PR makes immutable only files generated by Remix, which contain an hash in the name. Files in public will be cached only for 1 hour instead.

Fix #9353
