Introduce Kafka-aware readiness and liveness health handling for the consumer. Readiness is now based on initial Kafka bootstrap instead of a fixed startup delay. The application stays unready until the blocking listeners have consumed up to their startup end offsets, and then remains ready for the rest of the pod lifetime. This includes both the entity listener and the relation-update listener. Liveness is now separated from bootstrap and tracks Kafka runtime health for registered listeners. It reacts to Spring Kafka runtime events such as non-responsive consumers, failed starts and stopped consumers, while using a grace period to avoid false positives from short interruptions. Normal lag and quiet topics do not make the pod unhealthy. Also add Micrometer metrics for bootstrap progress and runtime Kafka health, including bootstrap duration, pending partitions, runtime problem counters and unhealthy state gauges. Update actuator health group configuration and add documentation for the new startup/readiness/liveness model, Kafka-specific health behavior, metrics and Kubernetes probe configuration.
