[Repo Assist] Fix Windows CI: use 127.0.0.1 instead of localhost for test HTTP servers (#1648)

* Fix Windows CI: use 127.0.0.1 instead of localhost for test HTTP servers

On Windows GitHub Actions runners, binding Kestrel to 'localhost' fails
because it attempts to bind to both 127.0.0.1 (IPv4) and ::1 (IPv6),
and IPv6 socket creation is forbidden (SocketException 10013: WSAEACCES).

Using '127.0.0.1' explicitly avoids the IPv6 bind attempt and makes the
tests reliable on Windows CI.
