添加PM2配置中缺失的JWT_SECRET环境变量

问题：
- PM2启动时报错：JWT_SECRET environment variable is not set
- 所有客户端实例(梅州、云浮、揭阳、潮州、省局)都缺少JWT_SECRET配置
- 导致服务无法正常启动

修复：
为每个客户端实例添加独立的JWT_SECRET环境变量：
- 梅州(51703): docreview-jwt-secret-key-production-meizhou-2024
- 云浮(51704): docreview-jwt-secret-key-production-yunfu-2024
- 揭阳(51705): docreview-jwt-secret-key-production-jieyang-2024
- 潮州(51706): docreview-jwt-secret-key-production-chaozhou-2024
- 省局(51707): docreview-jwt-secret-key-production-province-2024

注意：
- 每个客户端使用不同的JWT_SECRET增强安全性
- JWT_SECRET用于生成和验证前端JWT token
- 必需配置，否则服务无法启动

现在PM2可以正常启动所有客户端实例
