Add KafkaBus multi-topic publisher mirroring Optiq KFK between ME and
downstream consumers. MECoreActor publishes orders, trades, and BBO
snapshots to Kafka when EUNEX_KAFKA_BROKERS is set. No-op stub compiles
when EUNEX_USE_KAFKA is OFF. Switch Docker from bitnami/kafka to
apache/kafka:3.9.0 (KRaft mode). Add .dockerignore, update docs.
