[BUG] --update-hypervisor flag not triggering updates

[shbatm]

Describe the bug
The --update-hypervisor flag was defined in config.py and its logic was implemented in server.py:442-443, but it was missing from the condition in cli.py:48-56 that triggers netbox_create_or_update().

This meant running netbox_agent --update-hypervisor would do nothing because the update method was never called.

Expected behavior
Running netbox_agent --update-hypervisor should update the hypervisor items.

Configuration file
Relevent section:

virtual:
  enabled: false
  hypervisor: True
  cluster_name: cluster-pve
  list_guests_cmd: |
    pvesh get /cluster/resources --type vm --output-format json | jq -r '.[].name'

Environment:

• OS: Debian GNU/Linux 13 (trixie)
• Netbox agent version master
