Review Comment:
   Done — renamed to `xasecure.audit.destination.opensearch`.
   
   The prior approach reused `xasecure.audit.destination.elasticsearch` for 
backward compatibility — since OpenSearch is wire-compatible with 
Elasticsearch, the initial thinking was to share a single namespace so 
operators familiar with the existing ES config wouldn't need to learn new 
property names. However, this conflated two independent systems: Ranger Admin's 
`ranger.audit.elasticsearch.*` properties (in `ranger-admin-site.xml`) are used 
for UI audit queries, while the dispatcher's `xasecure.audit.destination.*` 
properties (in `ranger-audit-dispatcher-opensearch-site.xml`) control 
dispatcher enablement. These two config namespaces don't interact, so reusing 
the ES name added confusion without any functional benefit. Clean separation is 
the right approach.
   
   Updated in both site XMLs (source + docker), the manager class, and tests. 
Verified end-to-end with the Docker stack — dispatcher starts, indexes audits, 
and health-checks pass.
