The `provider` cannot be changed once a configuration exists — create a new configuration if you need to switch providers.

When rotating credentials, you only need to send the fields you're changing. Re-submitting a masked sensitive value preserves the original secret, so it's safe to round-trip a `GET` response back to a `PUT`.
