fix(课表小组件): 三项修复——header 显示「年级+班级」、body 去班级行、空态改内联 SVG、表格换私有类名去掉全局竖线

- header 与下拉项显示 gradeName + className（「高一 1班」）
- body 单元格只显示科目，不再重复班级
- 空态由「CSS 背景图 + 空 div」改为模板内联 SVG + 「暂无课表数据」
- 表格类名 my-table → tt：避开全局 componets/_my_table.scss 带进的 #c7c7c7 竖线与 th #fafafa 灰底
- 表头去灰底并加 1px 分隔线(#e9edf1)，行间横线加深 #eef1f4，表头字色 #344449
