v4.2 冲刺版+每日推送+支付修复+全量代码评审

## 新增功能
- 冲刺版 ¥49.9/月：完整支付→激活→权益扣减链路
- 每日一题定时推送（@nestjs/schedule，早8点微信订阅消息）
- miniprogram-ci 编译上传脚本（scripts/upload-mp.js）

## Bug修复
- 套餐值统一：vip→growth/sprint（interview轮次限制、analyze次数检查）
- member/pay 移除开发绕过：改为订单校验后激活
- progress→report 参数名不匹配：id→interviewId
- result.vue resume.create() 参数传错（对象→独立参数）
- resume.vue analyze请求缺少Authorization header
- bank.vue contribution请求缺少Authorization header
- member.vue startPay() 缺少try/catch导致网络错误崩溃
- login.vue 调试面板 v-if="true" 生产泄漏

## 配置
- 微信支付生产证书就位（商户号1113760598）
- .env 清理冗余文件（删除.example/.production）
- WX_NOTIFY_URL 更新为 zhiyinwx.yzrcloud.cn

## 文档
- PROJECT-STATUS.md v4.1→v4.2，状态全面更新
- DEPLOYMENT.md 新增小程序编译上传章节、清理检查清单
