HCK-6956: upgrade Elasticsearch driver

[taras-dubyk]

Content

Upgrades reverse engineering from the deprecated elasticsearch (v16) package to @elastic/elasticsearch@7, which was already used by forward engineering for Apply to Instance.

Changes:

• elasticsearchClientFactory.js — moved client factory to shared location so both FE and RE use a single source of truth
• clientFactory.js — replaced with a re-export shim pointing at the shared factory
• api.js — replaced manual connectionParams construction with ElasticSearchClientFactory.getByConnectionInfo(); updated testConnection to async/await with ping timeout as second argument. Updated getCount/search/getIndexes to destructure { body } from responses
• SchemaCreator.js — updated getMapping, getSettings, getAliases to destructure { body } from responses
