refactor(vd960Loop): 算法回退到 DLD154V4B，四通道适配

- 用 DLD154V4B vd1_task/per_channel 替换 vds_task 复杂算法
- 移除 FUNCTION_B/二次判断/快速变化/多重确认等增强特性
- 保留平坦性离开算法 (CN200910309382)，每通道独立状态
- 灵敏度表改为 DLD154V4B 4级: {216,108,36,10} / {108,72,18,9}
- 清理废弃类型: FltHistoryManager, Loop_ACS_Info, StageRangeConfig 等
- 首次添加 vd960DBN 完整源码
