Enable actual scale-out in Kubernetes HPA configuration

[Copilot]

Autoscaling in the Kubernetes manifest was effectively disabled because the HPA min and max replica counts were both set to 1. This change updates the scaling bounds so the deployment can increase replicas under CPU pressure.

• HPA scaling bounds
  • Updated /k8s/ironoc.yaml for HorizontalPodAutoscaler to allow scale-out.
  • Kept minReplicas unchanged at 1; increased maxReplicas from 1 to 3.

spec:
  minReplicas: 1
  maxReplicas: 3
  metrics:
    - type: Resource
      resource:
        name: cpu
        target:
          type: Utilization
          averageUtilization: 80

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Pull request overview

This PR enables real horizontal scale-out for the ironoc-app-deployment Kubernetes workload by increasing the HPA’s maxReplicas, which previously prevented autoscaling from increasing replicas under load.

Changes:

• Updated the HorizontalPodAutoscaler spec.maxReplicas from 1 to 3 (keeping minReplicas: 1).
