refactor: 清理代码、优化结构

- 移除订阅消息相关代码(WxSubscribeMessageService、subscribeTemplateId配置)
- 提取Result类为独立公共类(common.Result)
- 拆分Controller: WxLoginController(登录) + AppointmentController(预约)
- 引入Lombok(@Data/@Slf4j/@RequiredArgsConstructor)消除样板代码
- 修正WxLoginResult字段命名(session_key->sessionKey+@JsonProperty)
- MySQL驱动升级mysql-connector-java->mysql-connector-j
- updateStatus SQL增加status='pending'校验防并发重复审批
- pom.xml配置spring-boot-maven-plugin排除lombok
