refactor(ui): 统一 SongItem 圆角、抽象 HistoryItem、新增 EmptyState、修复主题色

- SongItem 5 变体容器/图片圆角统一为 rounded-xl(12px)：
  BaseSongItem(rounded-3xl→xl) / Standard(img rounded-2xl→xl) /
  Compact(rounded-lg→xl) / List(rounded-lg→xl) / Mini(rounded-2xl→xl)
- 抽象 HistoryItem.vue：AlbumItem 和 PlaylistItem 提取共享 UI 组件，
  消除 ~80 行重复样式代码，同时迁移至内联 Tailwind class
- 新增 EmptyState.vue：统一空状态组件（icon + text，暗色模式完整适配）
- 动画时长：SearchItem 图片 hover duration-700→duration-500
- MobilePlayBar：进度条颜色 Spotify #1ed760→项目主色 #22c55e
