Add a "Response History" feature in the API client, so users can quickly view past API responses with timestamps and status codes in a dropdown.

Use Cases:

• Debugging: Check previous responses to spot issues without re-running requests.
• Testing: Compare responses over time to ensure the API’s consistent performance.
• Audit: Keep a handy record of responses for compliance or review.

Requirements:

• Show a dropdown of past responses with timestamps and status codes.
• Let users click each entry to view the full response.
• Store response history securely with an option to limit storage if needed.

This feature will make it easy for users to track and analyze response history effortlessly.
