feat(admin): 仪表盘添加分块进场动画与数字滚动

- StatCard 三张卡 animate-page-enter 阶梯入场(0/60/120ms),待审评论卡数据就绪后补挂入场类(180ms),近期文章行 animate-row-enter 逐行 stagger(50ms 步进)——动画挂在数据就绪的真实分支上,避免骨架屏截断
- 新增 CountUp 组件:数值 easeOutQuint 滚动(500ms),use_effect 内驱动保持渲染纯净;命中 prefers-reduced-motion 直接显示终值
- input.css 新增 row-enter 关键帧;reduced-motion 媒体查询补全 animate-page-enter/popover-enter/row-enter 覆盖(此前仅 page-enter 生效)
- BTN_SECONDARY 补 active:scale-[0.98] 按压反馈,与 BTN_PRIMARY 对齐
