Resiliency testing on prod-stable-spoke1-dc-iad2 runs March 9-13, including an AZ loss test on March 13. Our pods will be directly impacted. Scale dashboard-api and dashboard-ui deployments to 2 replicas and add pod anti-affinity rules to ensure replicas scheduled on different nodes/AZs. This ensures at least one replica survives an AZ shutdown.                                               
Changes needed:
    - Set replicas: 2 in both API and UI deployment manifests
    - Add podAntiAffinity with preferredDuringSchedulingIgnoredDuringExecution using topology.kubernetes.io/zone as the topology key
    - Verify resource quotas allow 2 replicas per deployment
    - Test that both replicas start and receive traffic

Acceptance criteria:
    - API and UI running with 2 replicas on different AZs
    - Service continues to respond when one replica is terminated
    - Deployed before March 9
