feat: 完成布局优化 - 操作列固定、批量按钮自适应、分类标签带数量

优化内容:
1. 表格布局:
   - 使用 calc(100vw - 160px) 确保表格不超出视口
   - 操作列 fixed='right' 固定在右侧，宽度 300px
   - 按钮 3 个后自动换行 (max-width: 200px)
   - 恢复合理列宽，不再过度压缩

2. 批量操作区域:
   - 容器改为 inline-block，宽度自适应按钮内容
   - 背景宽度与按钮总宽度匹配

3. 分类标签:
   - 显示数量 (如 '待处理 (20)')
   - 点击切换筛选，去掉误导的 'X' 图标

4. 删除功能:
   - 操作列增加删除按钮
   - 删除前弹出确认对话框

5. 系统日志:
   - 修复后端日志路径 (parents[4])
   - 404 时显示友好提示

6. 其他:
   - 左侧菜单宽度 160px
   - 所有功能保留 (登录、用户管理、批量操作等)
