Add fingerprintjs to CNAME trackers

https://dev.fingerprintjs.com/docs/subdomain-integration

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'
})
```
