Description of problem:

OVN-Kubernetes tries to assign more EgressIPs to a node than available capacity.

Version-Release number of selected component (if applicable):

4.16.46

How reproducible:
How reproducible:

Intermittent, but consistently reproducible when:

• Cluster has multiple nodes labeled with k8s.ovn.org/egress-assignable.
• Workload requires more egress IPs than a single node can support (e.g., > X secondary IPs on AWS).
• CNCC continues to assign new CloudPrivateIPConfig to the saturated node.

See OCPBUGS-60806

Actual results:

• CNCC keeps assigning new IPs to a saturated node.
• CloudPrivateIPConfig objects remain stuck in CloudResponseError.
• No automatic redistribution to other egress-assignable nodes.

Expected results:

• CNCC should detect that a node has reached its IP/ENI limit.
• Scheduler logic should redistribute new or failing CloudPrivateIPConfig objects to other available `egress-assignable` nodes automatically.

Additional info:

OpenShift version: 4.16.46
