Fix Runtime Health criteria: network, services, nvidia-fabricmanager

Network: green if at least one interface has IPv4 (drop PARTIAL state).

Bee Services: treat inactive as OK — oneshot services (bee-sshsetup,
bee-preflight, bee-network, bee-audit, etc.) complete successfully and
exit to inactive; only failed is a real problem.

nvidia-fabricmanager: add ExecCondition=bee-check-nvswitch drop-in so
the service is silently skipped (inactive, not failed) on systems
without NVSwitch hardware (e.g. H200 NVL with direct NVLink, no
NVSwitch chips). bee-check-nvswitch detects NVSwitch via lspci
(vendor 10de, class 0680).

bee-nvidia.service: add ConditionPathExists=/usr/local/bin/bee-nvidia-load
so the unit is a no-op if somehow present in a non-nvidia build.

bee-boot-status: read /etc/bee-gpu-vendor and exclude bee-nvidia from
CRITICAL/ALL on non-nvidia builds, preventing boot hang if the unit
is unexpectedly present.
