feat(自学): 自学重做——首页课程地图、读一课按项目分目录、代码块就地运行、学完给题做

- 顶栏「自学」进新的自学首页 /learn：接着学（按服务端记录，不再串到上一个学生）+ 按项目分组的课程地图
- 读一课：左边目录按项目折叠，正文加宽，右边本课大纲带练一练标记；去掉了不能运行的示例代码栏
- 正文里的代码块能改能运行，报错用题目页那套中文解释；读输入的代码出输入框
- 课末：练一练做到几道 → 学完了 → 老师挑的几道题（必会标出来）→ 下一课
- 练一练统一成绿色提交、结果一行字；手机版目录从底部弹出
- 后台：教程列表按项目分组拖动排序，编辑页左写右看、练一练插到光标处、挑相关题；
  自学情况改成方块格 + 还没打开过的名单
