fix(net): stop per-request clients parking connections to remote hosts

Browse Source 
The node certificate probe builds a transport for one request and dropped
it with the connection still parked, and the remote routing client kept
idle connections with no timeout; either stayed open for as long as the
remote side wanted. Close the probe's idle connections when it returns,
and turn keep-alive off for routing downloads, which are minutes apart.
The routing client dials only public hosts, so no loopback test reaches
it; TestFetchCertFingerprintLeavesNoIdleConnection covers the probe.
