Fix Kiali trace correlation by setting explicit canonical-name labels

Adds service.istio.io/canonical-name pod labels to BigBang packages so that Kiali's trace queries match the service names stored in Tempo. Labels are conditionally applied only when Kiali is enabled, ensuring no impact to deployments without Kiali.
