refactor(energy): 简化事件驱动系统（7个→3个）

- 删除旧事件：BillApprovedEvent, BillCreatedEvent, DeductionCompletedEvent, DetailAuditedEvent, DetailCreatedEvent, RecordMatchedEvent
- 新增事件：BillAuditPassedEvent, DetailAuditPassedEvent
- 保留事件：RecordImportedEvent
- 更新监听器：AccountEventListener, BillEventListener, DetailEventListener
- 清理代码中的旧事件引用和注释

优化原则：前端简单，后端健壮
事件流程：导入→匹配→生成明细→审核→扣款→生成账单→结算
