fix(ops): 修复事件重复发布问题并清理遗留代码

1. 移除 OrderStateMachine 中重复的事件发布逻辑
   - OrderStateMachine 不再发布 OrderStateChangedEvent
   - 事件发布统一由 EventPublishHandler 处理

2. 删除 enqueueAndDispatch 遗留方法
   - 该方法已无用，被 DispatchEngine 策略模式替代
   - 删除接口声明、实现类和测试用例

3. 清理无调用的备用接口方法
   - enqueueOrderOnly、dispatchToCleaner、confirmOrder、
     startWorkingOnBeacon、autoCompleteOnSignalLost、
     playVoiceForNewOrder、playVoiceForQueuedOrder、
     playVoiceForNextTask、upgradePriorityToP0、
     calculateActualDuration
   - 保留接口但标记 @Deprecated

问题修复：
- 工单派发时 TTS 语音播报不再重复触发
- 调度逻辑统一走 DispatchEngine 策略模式
