/**
 * 批量修补所有 api-config.json 的 errorHandling.balanceInsufficient:
 *   1) 添加 `mess` responseField 检查 (voc-social-api 返回 `mess` 而非 `message`)
 *   2) 在 msg/mess/message 的 contains 列表中追加 "没有开通"、"权限或余额"
 *
 * 目标是让后端 403 `{"code":403,"mess":"没有开通社交平台API权限或余额不足"}`
 * 正确触发 onBalanceInsufficient 流程（而非被错误路由到 onMissing）
 *
 * 运行: node scripts/tools/_patch-errorhandling.js
 *       node scripts/tools/_patch-errorhandling.js --dry-run
