/**
 * 生成「老师组卷 + 学情分析」周报 PDF（与 report_teacher_weekly_stats.php 同源数据）
 *
 * 用法：
 *   php scripts/report_teacher_weekly_stats_pdf.php
 *   php scripts/report_teacher_weekly_stats_pdf.php /path/to/out.pdf
 *
 * 输出：
 *   - teacher-weekly-stats-{Y-m-d}_{His}.pdf（His = 24 小时制六位数字时分秒，如 143052）
 *   - 不配 latest 文件名；后台「打开 PDF」会自动选目录内最新的一份带时间戳 PDF。
