Return accumulated errors when Config API is absent.

argocd-operator/controllers/argoutil.VerifyAPI can return (false, nil) when the requested API is absent and an error for a separate discovery failure. Therefore, a Route API error can coexist with configAPIFound == false, and InspectCluster() currently discards that error.

Return stderrors.Join(errs...) on the missing-Config path instead of returning nil.

minimal, and validate.

In `@controllers/util/util.go` at line 100, Update InspectCluster’s missing-Config
API path to return stderrors.Join(errs...) instead of nil, preserving any Route
API or discovery errors already accumulated while Config is absent.
