🔊(oidc) improve logging for improperly configured authorization clients

Enhance the log message to explicitly list which configuration
parameters are missing.

The previous message was too vague and required searching the
repository to understand its origin. This was made harder because
the class name is dynamically injected, preventing a direct search
of the full log string.

Note: instantiating JWTAuthorizationServerClient may emit two logs
when all required parameters are missing. This behavior can be
refined in a future change.
