feat(ts): add toString() serialization to API responses

Add toString() to response objects returned by client.call() in web,
node, and react-native SDKs so that string interpolation produces JSON
instead of "[object Object]". Uses a simple property assignment on the
plain object to remain fully non-breaking (preserves prototype, isPlainObject, etc).
