feat: initialize parent-bff service with full core features

add complete parent-bff implementation including:
- GraphQL endpoint with depth/cost validation
- ChildGuard越权校验 with redis cache and singleflight
- parallel orchestration with partial failure fallback
- three-level cache fallback strategy (Redis + LRU + downstream)
- Kafka consumer for cache invalidation and notification push
- opossum circuit breaker for downstream services
- Prometheus metrics and SLO alerts
- Helm chart for k8s deployment with multi-environment configs
- Grafana dashboard for observability
- complete unit and integration tests

- cors.go: CORS 中间件（CORS_ORIGINS 环境变量）
- recovery.go: panic 恢复 + uuid request_id
- security.go: 安全头 + 请求体 10MB 限制
- requestid.go: 请求 ID 注入
- health/health.go: /healthz + /readyz 健康检查
- main.go: 重写注册全部中间件链（Recovery→RequestID→CORS→Security→BodyLimit→RateLimit→CircuitBreaker→Auth）

## 2. 基础设施硬化（infra/）
- backup/backup-mysql.sh: MySQL 全量备份（mysqldump+gzip，按服务独立）
- backup/restore-mysql.sh: 恢复脚本
