PCD269: add EP_HELPER_AUTH_HOST glue + bump plugin tag (phase A.3)

wp-config.php: mirrors the existing ELASTICSEARCH_DOCS_HOST -> EP_HELPER_HOST
pattern for ELASTICSEARCH_DOCS_AUTH_HOST -> EP_HELPER_AUTH_HOST. URL suffix
is the new /send-attachments-auth route on docsapi (proudcity-elastic-docs-api
commit ee064f6).

composer.json: bumps proudcity/wp-proud-search-elastic to 2026.06.02.1320,
which is the plugin commit that adds the URL selector (wp-proud-search-elastic
commit f6c4be2). Bumped in all three places: require, repositories[].package.version,
package.source.reference.

No behaviour change yet for any site. Until a site has
ELASTICSEARCH_DOCS_AUTH_HOST set on its pod env, the plugin's URL selector
falls through to the existing EP_HELPER_HOST path.

Refs PCD269.
