feat: 初始化微信小程序后端骨架

- NestJS + TypeScript + Prisma + PostgreSQL 工程骨架
- 微信登录安全流程:服务端 code2Session 换 openid 后签发 JWT,
  session_key 缓存于 Redis,不信任前端 openid
- 统一响应/异常处理、JWT 全局鉴权(@Public 豁免)、Swagger 文档
- Prisma 全量核心 schema(用户/分类/商品/设计清单/地址/订单/支付/上传/定制任务)+ seed
- 业务模块空壳(商品/分类/设计清单/地址/订单/支付/上传/BullMQ 队列)
- Docker 多阶段镜像 + 本地/生产 docker-compose
- docs:密钥获取指南、COS SDK 移除记录
