### Feature Description In high-throughput messaging workloads, producer retries or network duplications often produce duplicate message keys within short time intervals. Upstream and downstream operators require visibility into business key duplication ratios, duplicate time delta distributions, and consumer group idempotency health scores. ### Proposed Solution 1. Introduce `TopicDeduplicationHealthReport` model tracking sample message key duplication rates, duplicate delta intervals, and idempotency health status. 2. Implement `TopicDeduplicationHealthService` to sample topic messages and calculate key collision and duplicate frequency. 3. Provide `TopicDeduplicationHealthController` with `/topic/dedupHealth.query` endpoint. 4. Add frontend `TopicDeduplicationHealthModal` visualizing duplicate ratios, duplicate key tables, and idempotency tuning guidelines. 5. Provide comprehensive controller and service unit tests. -- This is an automated message from the Apache Git Service.
