sat: collect NVLink status/errors, fix nv-hostengine restart via systemd

Browse Source 
Add NVLink port status (nvidia-smi nvlink -s), error counters
(nvidia-smi nvlink -e), and dcgmi nvlink status to the support bundle,
and enrich HardwarePCIeDevice entries with per-link telemetry.

Replace the raw nv-hostengine pkill/restart dance in bee-nvidia-load
with systemctl restart/start of nvidia-dcgm.service, and order
bee-nvidia.service Before= nvidia-dcgm.service and
nvidia-fabricmanager.service so modules/device nodes exist before
those units start.
