Add explicit property type declarations to IdpTokenRefresher, CredentialsController, OAuthController, and McpServerClient classes. This improves type safety and allows Psalm to properly infer types, eliminating MissingPropertyType and many MixedMethodCall errors. Also adds IClient import where needed and validates getSystemValue returns to ensure string types before use. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
