feat: 埋点采集模块落地——AnalyticsService + 登录/注册/退出三事件（M0 简化版，报告 13）

- AnalyticsService：trackEvent(name, props?)/identify(userId)/reset()；隐私红线本地校验（password/token/phone 等模式拒绝）；匿名 ID 持久化复用 session deviceId；sessionId 简化为每事件生成（M0）；网络失败静默丢弃（无重试，按规范） - 登录/注册成功挂接 auth_login_succeeded / auth_register_succeeded（durationMs）；失败挂接 _failed（failureReason）；退出挂接 auth_logout - TODO（工单允许部分挂接）：page_viewed（登录/注册/首页/个人中心各一次，M0 无路由埋点基础）；health_record_action（M2 档案实现后挂接）；auth_session_restore_*（Splash 恢复流程待完善）；队列持久化到 shared_preferences 分段（当前内存队列 max 500，满 20 触发上传） - 测试：flutter test → 34 passed（30→34，新增 analytics_service_test 4 例：字段/隐私拒绝/identify/reset）；flutter analyze → 86 issues（与上一波同源）；dart format → 1 changed Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
