feat(model): add UPnP/NAT-PMP config to CommonDevice (FIREWALL-057)

[unclesp1d3r]

Summary

FIREWALL-057 (UPnP/NAT-PMP Disabled) returns UNKNOWN because the CommonDevice model lacks UPnP configuration.

Missing Field

Control	Field Needed	OPNsense XML Path	Description
FIREWALL-057	UPnP.Enabled	<installedpackages><miniupnpd><config><enable>	UPnP/NAT-PMP service enabled

Context

UPnP allows internal hosts to automatically create port-forward rules, which is a security risk. OPNsense uses the miniupnpd package. The config is typically under <installedpackages>.
