wangfq 92887a3d92 feat(vd960DBN): 传感快照区落地 snapshot.c + BLE SNAP_STAT/QUERY/CLEAR

- snapshot.h/c: 64B 定长 SnapRec (头部16B + 4x12B 0xC0线圈数据原样)
  环形分区独立于事件日志, 快照区 = 总容量 - 固定区576KB - 事件区
- 线程模型: USART2 ISR 只打包+RAM暂存(8深满丢新), 主循环 snap_flush 落盘
  (iot_sensor_ingest 在中断上下文, SPI 45ms 擦除严禁进中断)
- dbn_ble_srv: SNAP_STAT(0x28)/SNAP_QUERY(0x29)/SNAP_CLEAR(0x2A)
  QUERY 上限 2 条 (64x2+2=130B, ODR 教训防御)
- iot_mqtt_srv: ingest 挂 snap_enqueue, publish_sensor 挂 snap_flush
  (放在 READY 检查前, 断网照常落盘)
- peripheral_main: offlog_init 后加 snap_init
- 清空审计: 写事件流 log_clear payload[0]=2
- 测试: test_snapshot.c 8 例全过, offlog/ble_offlog 回归全过
- 文档: DLD960_BLE协议 V1.02 + ROADMAP P1.2 状态 + devlog
