    **Added** support for `app.kubernetes.io/name` and `service.istio.io/canonical-name` labels
    when populating `source_app` and `destination_app` metric labels. The priority order is:
    `app` (for backward compatibility), then `app.kubernetes.io/name`, then `service.istio.io/canonical-name`.
    This allows users who only have `app.kubernetes.io/name` labels to have their metrics properly populated.
