ddadmin 8e31b06241 fix(monitoring): correct Kafka metrics and alert rules ...

- Why:
  - dashboard showed offset as throughput and produced misleading values
  - kafka-exporter metric/label naming was inconsistent across alerts/docs
  - consumer-group-missing alert was noisy for demo runs
- What:
  - switch throughput panel to rate(kafka_topic_partition_current_offset[5m]) aggregated by topic and exclude __* topics
  - align lag metric/labels to kafka_consumergroup_lag + consumergroup
  - remove Kafka Consumer Group Missing alert from provisioning
  - pin kafka-exporter image to v1.9.0 and update OPERATIONS.md checks
- Check:
  - airflow dags list-import-errors -> No data found
  - Prometheus targets: clickhouse up, kafka up
  - PromQL kafka_consumergroup_lag returns series
  - Grafana dashboards provisioning reload returns success
