feat: webauthn (#2707)
This implements Webauthn. Old devices can be used to authenticate via the appid compatibility layer which should be automatic. New devices will be registered via Webauthn, and devices which do not support FIDO2 will no longer be able to be registered. At this time it does not fully support multiple devices (backend does, frontend doesn't allow registration of additional devices). Does not support passwordless.
