RSS doesn't work on actual deployments

[rozbb]

The RSS feed in server/src/list_articles.rs has a localhost URL. This makes it unusable in deployments.

The solution should be to have a new server flag --hostname that gives the hostname of the server (default localhost). Then the RSS fead can use that as the base of the URL path.

I belive I've hit this bug as well. I get a 404 on the api routes
