/**
 * One-time authentication setup. Logs in via the FastAPI backend directly
 * (skipping the UI) and persists the resulting localStorage token so every
 * test in the chromium project starts already authenticated.
 *
 * Mirrors the real auth flow in `lib/apis/auth-api.service.ts`:
 *   POST /auth/jwt/login  ->  { access_token }
 *   localStorage.setItem("surfsense_bearer_token", access_token)
 *
 * Requires a seeded test user in the dev/test DB. Configure via env:
 *   PLAYWRIGHT_TEST_EMAIL, PLAYWRIGHT_TEST_PASSWORD
 *   NEXT_PUBLIC_FASTAPI_BACKEND_URL  (defaults to http://localhost:8000)
