 +Proposed endpoints:
 +
 +- `/qr/*`: same as `/QR/*`
 +- `/QR/keys.json`: returns the public keys that are used to sign
 +- `/QR/<CODE>`: redirect to user-specific page or custom URL if we don't have this feature yet. This allows any user to scan this code as normal and be redirected to a nice webpage.
 +- `/QR/<CODE>/verify`: verify the signature ONLY (any client can verify themselves using the public key).
 +- `/QR/<CODE>/claims`: verify the signature and return the additional user claims.
