Inventory now declares the plural healthcheck_profiles list per host (hk2 runs
pdns, rustdesk, hk2aux) instead of a single healthcheck_profile, and carries
the rustdesk server vars (rustdesk_compose_dir/relay/image) plus the rustdesk
host group.
The restic role relied on the removed singular healthcheck_profile var; it now
uses its own restic_backup_profile (set per host to vaultwarden on us2 and pdns
on hk2), so the health-check rename no longer breaks it. audit.yml's summary
labels the host's profile list instead of the singular var.
