style: 切换为现代 SaaS Dashboard 风格（Linear/Vercel/Notion 风）

- 调色板：zinc 中性色 + 冷静蓝色（#3b82f6）+ 卡片阴影 token
- Sidebar：紧凑 60 宽度，加入顶部搜索框，分组导航，圆角 8px
- 卡片：rounded-2xl + shadow-sm/md，留白节奏统一
- 表格：圆角卡片包裹，灰色表头小写大写字母 tracking
- 表单：h-9 输入框，圆角 8px，focus ring 用半透明蓝
- 按钮分级：实心蓝（主操作）/ 边框白底（次操作）/ 暗黑实心（对比强调）
- 状态徽章：ring-1 inset 内边框，色板更柔和
