Use 127.0.0.1:10, matching existing refused-connection tests, instead of binding and releasing an ephemeral port that can be reused before the child process connects. Clear NO_PROXY and no_proxy so local proxy bypass settings do not skip the proxy connection attempt.

This deflakes the HTTP and HTTPS connection-refused proxy tests.
The tests previously bound an ephemeral port, closed it, and then expected a
child process to get
ECONNREFUSEDwhen connecting to that released port. Thatleft a race where the port could be reused before the child process connected.
This updates the tests to use
127.0.0.1:10, matching existingrefused-connection tests, and clears
NO_PROXY/no_proxyso local proxybypass settings do not skip the proxy connection attempt.
