Subject: [PATCH] fix(monitoring): order nvidia exporter after network-online

The nvidia exporter binds the host's static LAN IPv4, but unlike the node and smartctl exporters it was not ordered after network-online.target. On boot it lost the race with networkd, hit the systemd start limit, and stayed failed until manually restarted.
