fix(analytics): 系统性修复 Google Analytics 数据采集问题

- 修复城市 (not set): 移除 allow_google_signals: false，启用 Google 信号补充地理数据
- 修复 Consent Mode v2: 补充 ad_user_data / ad_personalization 参数
- 修复 wait_for_update 与横幅延迟不匹配: 500ms → 3000ms
- 修复 static export 兼容性: GA 初始化脚本从 client component 移至 layout.tsx head 原生 script 标签
- 修复 pageview 追踪: GA3 风格 gtag('config') → GA4 风格 gtag('event', 'page_view')
- 修复 CookieConsent: 横幅延迟 2000ms → 500ms，同意后补发 pageview
- 修复 PerformanceTracker: FID → INP (Core Web Vitals 2024 更新)
- 修复环境变量命名: NEXT_PUBLIC_GA_ID → NEXT_PUBLIC_GA_MEASUREMENT_ID
- 清理 deploy-dist.sh 冗余 server/app 分支逻辑
- 新增部署产物 GA 脚本嵌入验证
