Use Cloudflare CDN for static assets

Description of the issue 📄

During a past incident I learned that Rails is serving up static assets, which is completely unnecessary. We already have the domain set up with Cloudflare, so we may as well use their CDN and save some load on the Rails app.

Go look at the log files ;)
