我的页面：头像姓名并入会员卡，去掉学校信息

原先顶部渐变区单独一块「大头像 + 姓名 + 学校 + 学院专业标签」，
对用户实际没什么用，还占掉一屏顶部空间。

改动：
- 删除顶部个人信息块（含学校名与学院/专业/班级标签）
- 头像缩为 44px 圆形，移到会员卡内 Crown 图标的位置（该图标去掉），
  姓名与会员身份（VIP/普通用户）合并为同一行
- VIP 角标改为贴在头像右下角
- 顶部渐变条高度压缩：padding-top 28px→14px、pb-20→pb-16，
  会员卡仍以 -mt-14 上浮叠压，视觉层次不变

顺带清理不再使用的导入与计算属性：Crown 图标、GraduationCap 图标、
profileTags（学院/专业/班级标签）。
修掉 img 的 :src 缺可选链导致的 null 类型报错。

npm run build 与 vue-tsc 均通过。
