[BUG]: Fix service name extraction logic in go

[tanujnay112]

Description of changes

The logic to extract the service name in go code was wrong. The logic to generate the lock name for the sysdb service during leader election was dependent on this and was faulty as a result. Every replica ended up generating different lock names.

This diff fixes that issue.

It updates the extractServiceName helper to remove both the replica set hash and the pod hash suffixes from Kubernetes pod names so that every replica resolves the same {service-name}-leader lock key.

Key Changes

• Updated extractServiceName to drop the last two hyphen-delimited segments from pod names when available
• Clarified inline documentation to reflect Kubernetes deployment-style pod naming assumptions
