Public-cloud providers can only fill half of Catalog interface

seems Catalog interface mixes a generic "what instance types / prices / regions exist" surface with an internal capacity/supply model that public clouds can not populate

ListInstanceTypes / ListPricing / ListRegions => seems these are public cloud fillable.
ListResources/ListResourcePredictions/ListPricingPredictions can not be used in public cloud at this moment

expected or not?

NewCatalog(provider, args...) is constructed without a credential at startup, but live pricing/capacity needs an API key — both providers had to degrade to static tables
