refactor: 配置刷新优化和加密功能移除

- refactor(springboot2): 简化配置刷新逻辑，移除 EnvironmentChangeEvent 包装
  - ConfigChangeHanlder 直接接收 Map<String,String> 参数
  - 移除 EnvironmentChangeEvent 事件类
  - 优化 token 参数构建和敏感信息脱敏处理
- refactor(server): 移除配置加密功能
  - 删除 CryptoConfig 结构体和相关配置项
  - 移除 application-dev.properties 中的加密配置
  - 项目不再使用配置加密功能
- docs: 更新 README 和模块文档
- fix: 修复 Node.js 客户端配置缓存
