Response Examples

> ℹ️ _This issue was partially AI-generated and may contain technical inaccuracies._

**Is your feature request related to a problem? Please describe.**
Requests cannot store example responses, so there is no built-in documentation of expected responses and no source for a mock server.

**Describe the solution you'd like**
Allow saving one or more example responses per request (status, headers, body), shown alongside the request as documentation.

**Describe alternatives you've considered**
Keeping examples in external docs or comments.

**Additional context**
Foundation for the Mock Server (#842) and API Docs auto-generation (#859).

The issue names no files or tests. Start by locating how requests are stored and displayed, then determine where example responses belong and how they should appear alongside a request. Done means one or more examples can be saved with status, headers, and body, and are available as request documentation.
