• Show baseline status per pod: learning / established / anomaly
• Show top anomalous pods sorted by deviation score
• Show per-rule FP rates
• Pull from GET /baseline/:namespace/:pod

Acceptance criteria

• Dashboard shows all pods with baseline status
• Anomaly score visible per pod
• FP rate visible per rule
• Filters by namespace
