Jon Shea eac35d441c Add client_secret_basic authentication support 
Add support for HTTP Basic Authentication (client_secret_basic) as a
client authentication method for the token and revoke endpoints, alongside
the existing client_secret_post method. This improves compatibility with
OAuth servers like Keycloak that use Basic auth.

Key changes:
- Update OAuthClientMetadata to accept "client_secret_basic" as valid
  token_endpoint_auth_method
- Return 401 status for authentication failures (was 400)
- Update metadata endpoints to advertise both auth methods
- Add tests for both auth methods and edge cases
