在这个一次性练习项目中修复 report.mjs，使 totalPaid 只统计 paid 行。先读 orders.csv 和 report.test.mjs，执行 node --test report.test.mjs 并报告原始失败。不要改 orders.csv、report.test.mjs 或 report.original.mjs；不要安装依赖或访问其他目录。以最小实现修改完成修复，重跑全部三项断言，并根据 orders.csv 计算总额。最后列出修改文件、实际测试结果、总额和局限。命令因环境原因失败时，请与断言失败明确区分。

node --test report.test.mjs
node --input-type=module -e "import {readFileSync} from 'node:fs'; import {totalPaid} from './report.mjs'; console.log(totalPaid(readFileSync('orders.csv','utf8')))"
diff -u report.original.mjs report.mjs

cp report.mjs report.attempt.mjs
cp report.original.mjs report.mjs
node --test report.test.mjs
