Add fingerprintjs to CNAME trackers

We need to figure out what domain they use for CNAME tracker (not clear from the doc yet, could be acm-validations.aws.).

Let's use publicwww and look for their scripts that use custom endpoint:

const fpPromise = FingerprintJS.load({
  token: 'your-browser-token',
  endpoint: 'https://fp.yourdomain.com'
})
