 * Routes:
 *   - GET/POST /api/search/settings/global-search  (POST requires search.manage)
 *   - GET /api/search/search/global                 (ignores any `strategies` URL param)
 *
 * Saves enabledStrategies = ['tokens'], then calls global search with a
 * conflicting ?strategies=fulltext,vector and asserts the response's
 * strategiesEnabled reflects the SAVED config, not the URL. The original config
 * is restored in `finally`. `admin` holds both search.view and search.manage.
