…s from CIDR Use `ansible.utils.nthhost(1)` to derive the bridge gateway IP directly from the network CIDR instead of requiring a hardcoded `gateway` field in `values.yaml`. This ensures the `internalapi` and `storage` bridge gateway addresses in BGP deployments are always consistent with the configured subnet. Required by the NNCP fix in the `architecture` repo (OSPRH-32725), where the NNCP desired state must include the bridge gateway IP so NMState does not remove it during periodic reconciliation cycles, which otherwise causes `ovn-controller` to lose connectivity to the OVN SB DB pods.
