Bug 37170

I am experiencing an issue with the Koha "About Koha" page. Although Elasticsearch is functioning correctly (indices are being rebuilt, and records are searchable), the "About Koha" page displays Elasticsearch status as "not running."

Steps to Reproduce:

Set up Koha with Elasticsearch as the search engine.
Successfully rebuild Elasticsearch indices using the command:

docker exec -it koha koha-elasticsearch --rebuild --verbose -d mylibrary

[436] Checking state of biblios index
[436] Dropping and recreating biblios index
[436] Checking state of authorities index
[436] Dropping and recreating authorities index
[436] Indexing biblios
[436] Committing final records...
[436] Total 1 records indexed
[436] Indexing authorities
[436] Committing final records...
[436] Total 1 records indexed

Perform searches in both OPAC and Staff interfaces, confirming that records are searchable.
Navigate to the "About Koha" page.

Expected Behavior:
The "About Koha" page should display the Elasticsearch version, number of nodes, and status as running.

Actual Behavior:
The "About Koha" page displays:

Elasticsearch: Version: | Nodes: | Status: not running
