toNicDevice() unconditionally required a managed network: (via Config.Network or Config.NetworkName), even though Extensions already carries everything an unmanaged-bridge NIC device needs (nictype + parent). Incus itself accepts this device shape directly -- the validation here was stricter than the daemon it targets.

Only reject when neither a managed network nor nictype is present, matching Incus's own two valid ways to declare a NIC. network: is also no longer forced into the device map when unset, so nictype based devices don't pick up an empty network="" key.

Adds TestNicDevices (regression case fails against the prior code with the exact reported error, "bad config for device eth1") and a narrow- scoping error case confirming an unrelated extension alone still errors.

toNicDevice() unconditionally required a managed `network:` (via

Only reject when neither a managed network nor `nictype` is present,
matching Incus's own two valid ways to declare a NIC. network: is
also no longer forced into the device map when unset, so `nictype`
based devices don't pick up an empty network="" key.

Adds TestNicDevices (regression case fails against the prior code with
