feat(dify): 增加基于 appType 的应用查询功能并优化异常处理

- 在 AppEntity 中添加 AppType 枚举字段，用于区分不同类型的 app
- 在 AppEntityService 中新增 getAppsByAppType 方法，根据 appType 获取应用列表
- 在 AppEntityServiceImpl 中实现 getAppsByAppType 方法，使用 LambdaQueryWrapper 进行查询
- 在 V1ServerController 中添加 getAppsByAppType 接口，提供基于 appType 的应用列表查询
- 优化 ExceptionUtil 中的异常处理，统一使用 difyException 方法处理异常- 在 V1ChatController 和V1WorkflowController 中使用新的 difyException 方法处理异常
- 移除 MybatisPlusConfig 中未使用的代码，简化配置
