Consider handling IPv6-mapped IPv4 addresses for localhost.

Also include '::ffff:127.0.0.1' in the internal connection check to cover IPv6-mapped IPv4 localhost addresses.

## Overall Comments
- Consider using a CIDR-based or net.isLoopback utility instead of hardcoding specific loopback address strings to cover all IPv4/IPv6 variants.
- If the app sits behind a reverse proxy, req.socket.remoteAddress might not reflect the original client; ensure you handle X-Forwarded-For headers or configure trusted proxies.
- You could extract the localhost check into a reusable helper to keep the controller code concise and improve testability.

<issue_to_address>
Consider IPv6-mapped IPv4 and proxy scenarios for localhost detection.

This check may not handle all localhost scenarios, such as alternative IPv6-mapped formats or proxy headers like X-Forwarded-For. Consider updating the logic or documenting these limitations if relevant to your deployment.
