Replace pkg/iam/scopeset with pkg/iam/oauth2scope.Registry, a shared OAuth2 scope→action registry used by the authorizer, OAuth2 service, and Connect API. Registration stays open until probod calls Freeze(); read paths (RegisteredScopes, Allows, ValidateScopes) panic before that. Drop the leaky APIScopes surface and AllowedAPIScopes on manual access-token creation in favor of registry.ValidateScopes. Metadata, protected-resource metadata, and CIMD scope lists are built from RegisteredScopes() via helpers in pkg/iam/oauth2/scopes.go. Expose oauth2ScopesSupported as an OAuth2Scope GraphQL scalar.
