style: 重做整体视觉系统（编辑设计 × 建筑精度）

- Fraunces 衬线 display + DM Sans body + JetBrains Mono 数字标签
- 暖米白主题（#f7f4ee）+ 蓝色强调色（#2563eb）
- 引入 lucide-react 图标库替代 emoji
- Sidebar 加入编号索引、Logo、用户区域、杂志风分组标题
- 产品列表页加入大号 display 标题、搜索、卡片悬浮动画
- 产品详情页面包屑、tab 编号、需求表格重做
- 状态徽章改为色点 + 文字，"已拒绝"用红色避免与"评审中"冲突
- 全局加入 grain 噪点纹理、入场交错动画
