get_facts read hostname and version from /api/core/system/status, which on
OPNsense 26.7 carries neither: every firewall read as nameless and "unknown",
and netOrk kept naming one by its address. /api/diagnostics/system/system_information
has both (name is the FQDN, versions[0] "OPNsense 26.7.7-amd64"). The status
answer still counts where the new one gives nothing.
get_interfaces_ip listed each interface's primary address only, so a CARP address
never showed as the holder's. It now lists an address bound to a VHID on the node
that is MASTER for it, and leaves it off a BACKUP -- as keepalived puts the address
on the master alone. netOrk's VIP badge sits on that interface (netOrk #1121).
