feat: 完成项目整理优化和生产环境配置

🧹 项目结构优化:
- 删除重复和过时的文件
- 整理文档到docs目录结构
- 优化配置文件到configs目录
- 创建清晰的PROJECT_STRUCTURE.md

🔧 中间件配置:
- 重启MySQL/Redis/Nacos中间件
- 使用现有数据目录，确保数据完整性
- 统一密码配置: MySQL(EmotionMuseum2025*#), Nacos(Peanut2817*#)

🌐 Nginx配置:
- 配置前端路径: /emotion-museum
- 配置API代理: /api/ -> 19000
- 配置WebSocket代理: /ws/ -> 19007
- 添加健康检查端点: /health

📋 部署脚本优化:
- restart-middleware.sh - 中间件重启脚本
- setup-nginx.sh - Nginx配置脚本
- cleanup-project.sh - 项目清理脚本
- one-click-deploy.sh - 一键部署脚本

📖 文档完善:
- DEPLOYMENT_FINAL.md - 最终部署指南
- PROJECT_STRUCTURE.md - 项目结构说明
- 完整的运维和故障排查指南

✅ 生产环境就绪:
- 中间件: MySQL/Redis/Nacos 运行正常
- Nginx: 反向代理配置完成
- 访问地址: http://47.111.10.27/emotion-museum
- 健康检查: http://47.111.10.27/health

🎯 项目现状:
- 10个微服务模块完整
- 前后端分离架构
- 容器化部署
- 统一配置管理
- 完整的部署和运维体系
