- add OAuth flows for:

- sign-in
- sign-up
- re-authenticate
- add custom `oauth-ghost` authenticator to support our custom data structure
- add test helpers to stub successful/failed oauth authentication
- hide change password form if using OAuth (temporary - a way to change password via oauth provider will be added later)
