Added nginx-unit.json as a ConfigMap and patched the NetBox deployment to mount it, bypassing IPv6 listener issues ([::]:8080) inside vClusters where IPv6 is not enabled.

@pablogarciamiranda great work on pinpointing the issue! Just a question: Is it a vCluster related issue or rather an issue related to the underlying Kubernetes (e.g. Kind, EKS, ...) that lacks IPv4 support? If it's vCluster specifically then all is good. If not, I would propose to rename "IS_VCLUSTER" to "FORCE_NETBOX_NGINX_IPV4" and the PR to something like "Fix NetBox NGINX deployment for IPv4 only environments". |

This PR addresses a bug where the NetBox pod fails to start inside a cluster without IPv6 support, because NGINX Unit tries to bind to an IPv6 address ([::]:8080).
What’s changed:
Why:
NGINX Unit fails to apply its configuration in clusters with lack of IPv6 support, which blocks NetBox from becoming ready and causes the Helm release to hang.
