Subject: [PATCH] fix: add persistent volumes for Redis, RabbitMQ, Zookeeper,
 and Kafka

Add Docker named volumes for Redis, RabbitMQ, Zookeeper, and Kafka
services to prevent data loss on container restart.

Previously only Postgres and MongoDB had persistent volumes, causing
session cache, message queues, stream data, and Zookeeper state to
be ephemeral.

- Redis: redis_data -> /data
- RabbitMQ: rabbitmq_data -> /var/lib/rabbitmq
- Zookeeper: zookeeper_data -> /var/lib/zookeeper/data,
  zookeeper_log -> /var/lib/zookeeper/log
- Kafka: kafka_data -> /var/lib/kafka/data

Fixes #57
