feat(MCN工作台): 数据功能页+图标扁平化+多项UI优化

- 工作台大版本升级：hash 路由 + 6 数据功能页（周榜/热门账号/账号详情/视频详情/AI写脚本/AI写作复盘），只读复用 dsh 库副本 + 抖音榜单 JSON
- 数据库隔离：复制 dsh 库到 mcn-work-shop/，与 dsh 原库各访问各的（已 gitignore）
- 图标全面扁平化：Lucide 线性 SVG，功能图标亮色区分，文字标题去图标
- 首页重构：功能入口卡 + AI写剧本快捷卡片(2列/8个/5行预览) + 独立帮助页 + header 精简
- 新增设计技能 impeccable + taste-skill（生成网页时参考）
- 修复：fmtTime 跨 script 全局冲突(P0)、弹窗关闭、外链新标签打开等
