fix trading-kafka: remove invalid template.pod.brokers, add controller role to KafkaNodePool

- Removed template.pod.brokers (not valid in Strimzi 1.0.0 Kafka schema)
- Moved broker resources to KafkaNodePool.spec.resources
- Added controller role to KafkaNodePool (KRaft requires both controller+broker)
