如何修复Tailwind侧边栏中Logout按钮未显示在底部的问题？

你需要给侧边栏的<nav>元素补充flex类，同时调整Logout区域的内边距样式，就能实现按钮贴底的效果。

关键修改点说明 #

1. 给<nav>添加flex类：原代码中<nav>只加了flex-col和justify-between，但缺少核心的flex类，导致弹性布局不生效。添加后，justify-between会让容器内的两个子元素（顶部菜单区和底部Logout区）分别靠上、靠下对齐，中间自动填充空白区域。
2. 调整Logout区域的内边距：将原来的pb-10 pl-10改为px-4 py-2，和上方菜单项的内边距保持一致，保证视觉风格统一，同时移除了多余的bg-white（因为<nav>已经设置了背景色）。
