fix(web): 1:1 对齐——页头通栏、内部滚动、侧栏菜单与详情导航

- Layout: screen 模式下约束 body/main 高度，恢复内容区内部滚动（原来内容把根撑高被裁切）
- Layout: contentOffset=88，滚动区从页头下方开始，内容不再从悬浮搜索框下穿过
- 页头改回通栏 60px（contained 只包页身）；资料卡头像恢复 64px 图标 + 品牌底色
- 详情导航条左右撑开（返回 / 面包屑），不再挤在左侧
- 侧栏菜单：行高 39、字重 500、圆角 8、CSS chevron、项间距 4px
- 服务面板去掉多余分隔线与外边距，恢复原高度
