Gateway sign-in config now uses inferenceCredentialKind; the old key still works but warns.
What's wrong with this entry?
Managed and desktop gateway configuration now sets inferenceCredentialKind: "interactive" in place of inferenceGatewayAuthScheme: "sso". The old key still works but logs a deprecation warning and is rewritten to the new one, so existing managed settings keep working without edits.
- New validation messages cover credential kinds a given provider does not support.
- Desktop overlay values are merged through a dedicated overlay step rather than spread verbatim over the base config.
inferenceGatewayAuthScheme: "sso" is deprecated; set inferenceCredentialKind: "interactive" instead.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
