优化派单逻辑并清理无用引用

在 `OrderController.cs` 中：
- 修改派单节点处理逻辑，使用 `MaxBy` 方法获取最新节点，删除重复代码，增加 `sendOrderTrace` 的空检查。
- 修改平均派单处理逻辑，将 `averageSendOrder` 判断移到 `nextDto.NextHandlers` 检查之后，删除重复代码。

在 `StartupExtensions.cs` 中：
- 删除 `Hotline.Application.Contracts`、`Hotline.ThirdAccountDomainServices.Interfaces`、`Hotline.Snapshot.IRepository`、`Hotline.Validators`、`Hotline.Api.Filter`、`Hotline.Caching.Interfaces` 和 `Hotline.Caching.Services` 的引用。
