feat(theme+规范): 管理端接入 yh-theme 主题层并按 bsch 应用页规范升级页面骨架

- 主题层: scripts/gen-yh-theme.mjs 生成 assets/styles/yh-theme.css(构建期静态化 color-mix),
  5 主题档×侧栏深浅×渐变×side-plain 挂 html 档位类名; main.ts 于 icons.css 后引入并 initTheme() 消首帧闪色
- utils/theme.ts(+8 用例): localStorage(yh-theme) 持久化 + <html> 档位类名幂等切换
- ThemeSwitcher.vue(+6 用例): 顶栏配色胶囊(5 色网格+3 开关), 定稿 07-seam-pure 同款皮肤
- SchoolLayout: 顶栏 logo 徽标+配色切换器挂载; 站点身份色带退役, 子站橙由 yh-theme .band-sub::before 融合
- useTableHeight 响应化(+5 用例): ResizeObserver(body) 重算修复窗口缩放冻结, 常量 56/56 档不动
- bsch 规范骨架: 操作区 fix mb-12/次按钮 fr, Table 补 link-table table-bottom-box,
  文章关键字 200px 即输即搜(300ms 防抖去 enter-button), 附件分页 customPageCount 记忆+page-box fr,
  轮播展示位移入搜索区, 友链分组改 tabs-wrapper+Tabs card, 五表单校验失败统一"请填写红色星号内容！"
