fix(gcprouternatgateway): correct metric prefix gcp.compute.nat → gcp.router.nat

gcp-polling-v2 polls NAT metrics under router.googleapis.com (see
gcp-entity-definitions.yml: monitored_resource_type nat_gateway maps
to metric_prefix router.googleapis.com), so NR emits them as
gcp.router.nat.*, not gcp.compute.nat.*. Golden metrics + dashboard
were querying the wrong prefix and returning zero rows.

- golden_metrics.yml: 3 metrics
- dashboard.json: 9 widget queries (open_connections, sent_bytes_count,
  dropped_sent_packets_count, allocated_ports, received_bytes_count,
  new_connections_count, port_usage)
