add calculated public node to the deployed network object

[Omarabdul3ziz]

Problem

in case a public node was calculated while deploying a node for first time, the public node is added in the fields (NodeDeploymentIDs, WGPorts, Keys, ..) but not in Nodes

in case an update happens to the network, constructing the peers fails cause ip wasn't fetched for the public node, only we have it's ip. so it ends up with endpoint like this `":"

this gives the error

failed to configure network resource: failed to configure wireguard interface: failed to configure wireguard interface: wglinux: invalid endpoint IP: <nil>

Solution

just making sure the calculated public node is added to the znet object after the deployment is done
