As a WME engineer, I want to add health checks for Kafka, Redis, and the Schema Registry to Structured Data Service using the WME SDK so that the service can expose a single /healthz endpoint for readiness and liveness monitoring.

*TO DO*

• Add health Checks to structured data
• Merge MR in service deploy to expose health checks in dev
• Merge MR in service deploy to expose health checks in prod

*Acceptance Criteria*

• Kafka and Schema Registry health checks implemented using WME SDK
• All checks exposed via the /healthz endpoint
• All checks are propagated to both dev and prod
