feat(detail): Layer 3 信任层空数据兜底骨架(L3SignalsSlot + L3EmptyFallback + EarlyAccessNotice)

- 新增 L3SignalsSlot:4 类可验证替代信号卡(方法论/团队/历程/服务承诺),
  服务承诺卡 disabled 占位待业务确认;零编造约束下替代真实案例/认证
- 新增 EarlyAccessNotice:首批客户共创状态条(单一真源 company.ts EARLY_ACCESS)
- 新增 L3EmptyFallback:caseStudies/certifications/dataProofs 三者全空时渲染兜底,
  任一非空 return null 保留本地真实 section 视觉
- 接入 5 处详情页:solution v3 / service v4 / product v3 / erp-upgrade-v3 / standalone/[id]
- 修复 StaggerReveal 网格布局:grid 类须挂在 StaggerReveal 自身(否则卡片堆单列)
- 更新 solution 测试至新行为(空数据→兜底渲染)+ 补 lucide 图标 mock
- 修复 header.test.tsx 双 logo 断言(2593599 遗留)
- 新增 scripts/audit/l3-fallback-verify.mjs 运行时验证(浅/深双版 PASS)
  注:必须用 localhost 而非 127.0.0.1 —— Next dev allowedDevOrigins 默认白名单
  不含 127.0.0.1,chunk 请求带该 Origin 被 403 → hydration 不发生 → 动画全冻结

验证:type-check 0 错 · lint 0 错(127 既有 warnings) · 单测 129 套件/1628 通过 ·
L3 兜底浅深双版渲染截图 PASS

// 验证 Layer 3 空数据兜底(L3EmptyFallback):信号卡 + 共创占位渲染
// 用法:node scripts/audit/l3-fallback-verify.mjs
//
// 断言(solution 详情页,当前无 caseStudies/certifications → 兜底应渲染):
// 1. section[aria-labelledby=l3-signals-heading] 存在且可见(opacity→1
// 2. 4 张信号卡齐全,其中 3 张为链接(/methodology /team /about/brand),1 张 disabled
// 3. EarlyAccessNotice(首批客户共创中)存在
// 4. 深色模式下同样成立(截图目视 + token 反色由 globals.css 变量层保证)
