fix(databus): 修复客户端消息处理和防止消息循环

Browse Source 
1. 修复消息格式不匹配问题
   - 增量消息：兼容 SyncMessage 格式，从 dataSnapshot 字段反序列化数据
   - 批量消息：添加 getDataType() 方法获取泛型类型，正确转换 JSONObject

2. 防止消息循环
   - 添加 zt.databus.change.producer.enabled 配置项
   - 客户端禁用变更消息发送，避免 客户端写入 → 发送变更 → 循环

3. 修复 Feign 客户端注入
   - 在 RpcConfiguration 中添加 DeptApi、PostApi
   - 确保客户端能通过 Feign 调用本地 system-server API

相关文件：
- DatabusClientConsumer.java: 修复消息解析逻辑
- BatchSyncEventHandler.java: 添加 getDataType() 方法
- DatabusChangeProducer.java: 添加 enabled 开关
- RpcConfiguration.java: 启用 DeptApi/PostApi Feign 客户端
