fix(andon): 修复安灯事件派工状态更新和自动分配逻辑, 当PDA使用/production/andon/mobile/call接口提交安灯呼叫时，将时间设置为安灯派工AndonEventAssignment的acceptTime，当安灯事件结束后设置时间为安灯派工AndonEventAssignment的finishTime

- 移除ACCEPTED状态下的acceptTime自动设置逻辑，仅保留DONE状态的finishTime设置
- 重命名autoCreateAssignments方法中的参数名从e改为event以提高可读性
- 在PDA调用场景下为自动创建的派工记录立即设置acceptTime表示已接单
- 更新变量名从a改为assignment，提高代码可读性
- 修复方法内部对event对象的引用保持一致性
