Fix weathermap links to show both traffic directions

Browse Source

Z side queried z_host's rx, which measures the same A->Z flow as A
side's tx (same traffic, counted at each end) -- the Z->A direction
was never queried by either side. Use z_host's own tx instead, so
each side surfaces its own (opposite) direction.

Confirmed against the iperf3 traffic generator: DC access-leaf links
read ~500Kbps (ACK-only) before the fix despite ~18-20Mbps of real
downstream traffic to dc-server2/4, because that flow ran leaf->access
(Z->A), the unqueried direction. Campus links looked correct only by
coincidence -- campus hosts are the iperf3 clients, so their upload
traffic happens to run access->leaf (A->Z), the direction that was
queried.
