/**
 * 03-admin-plugins.spec.ts
 *
 * What: Verifies all five peptiderepo plugins are active in wp-admin and
 *       their admin pages load without PHP errors. Catches activation failures
 *       or missing plugin files after a deploy.
 * Who triggers it: Playwright chromium project (post-auth setup).
 * Dependencies: wp-admin authenticated session (from global.setup.ts).
 *
 * Plugin admin page slugs:
 *   - peptide-search-ai       → ?page=peptide-search-ai
 *   - pr-autoblogger          → ?page=pr-autoblogger
 *   - peptide-repo-core       → ?page=peptide-repo-core  (if admin page exists)
 *
 * @see C:\Users\ongte\apps\Peptide Repo CTO\app-maps\
