List and delete Pulsar topics in a namespace

Steps

1. List all persistent topics in a namespace: pulsar-admin topics list {tenant}/{namespace} — this returns persistent:// URIs for all topics.
2. To include partitioned topics, also run: pulsar-admin topics list-partitioned-topics {tenant}/{namespace}
3. Check if a topic has any active subscriptions or producers before deleting: pulsar-admin topics stats {tenant}/{namespace}/{topic-name}
4. Delete a non-partitioned topic: pulsar-admin topics delete persistent://{tenant}/{namespace}/{topic-name} — add --force if there are active producers or consumers you want to force-close.
5. Delete a partitioned topic: pulsar-admin topics delete-partitioned-topic persistent://{tenant}/{namespace}/{topic-name}
