        /* ── 「调整映射」弹窗：只保留一层滚动容器 ───────────────────────────
           2026-10-26 生产反馈：「调整映射里向下滑动很难滑动」。
           两个原因叠加：
           ① 表格外层是 Bootstrap 的 .table-responsive（overflow-x:auto）。
              只要一个方向不是 visible，另一个方向就会被计算成 auto，
              于是表格容器变成**第二层滚动容器**，鼠标停在表格上往下滚时
              滚轮被它吃掉，表现就是「怎么滚都滚不动」。
           ② 弹窗没有固定高度，.modal-body 不构成独立滚动区，
              整张 52 行的表格撑开弹窗，底部按钮被顶到视口外。
           现在：弹窗高度锁定视口、只有 .modal-body 滚动、表格不再横向滚动、
           表头吸顶（滚动时还能看清哪一列是题目、哪一列是 Excel 列）。 */
