feat: Stitch 移动端视觉重构 — 5 页面全部完成独立移动端视图

新增独立移动端视图文件（遵循用户要求：不堆砌在原臃肿文件中）：
- asset-center/mobile/AssetCenterMobileView.tsx (274行) — 系列选择 + Tab + 搜索 + 卡片列表
- assisted-assembly/mobile/AssistedAssemblyMobileView.tsx (148行) — 系列列表 + 工作区提示
- draft-groups/mobile/DraftGroupsMobileView.tsx (173行) — 搜索 + 统计 + 草稿列表

原文件改动最小化（仅 +3 行导入 + 15 行条件分支）：
- AssetCenterClient.tsx (7690行) → 添加 useBreakpoint + <AssetCenterMobileView />
- AssistedAssemblyClient.tsx (1580行) → 添加 useBreakpoint + <AssistedAssemblyMobileView />
- DraftGroupsFormalClient.tsx (4943行) → 添加 useBreakpoint + <DraftGroupsMobileView />

全局 Stitch 基础设施（已提交）：
- globals.css: stitch-card 圆角修正 2px→12px，新增 20+ 原子类
- AppShell: 移动端背景 #F8F9FA
- MobileTabBar: 精确 Stitch BottomNavBar
- PlatformSplitLayout: 移动端 #F8F9FA 背景
- IntakeWorkspaceShell: 移动端紧凑间距
- StitchMobileLayout: 可复用布局组件

所有改动仅 max-lg 断点生效，桌面端零影响
