feat(vd960DBN): 恢复快照区功能, 移除 sim_snap_spi 实验桩, UART2 波特率注释修正

Browse Source 
- peripheral_main.c: snap_init() 恢复 (去 #if 0), offlog_boot() 恢复
  (上电复位原因记入事件日志); 删除 sim_snap_spi 模拟写密度实验函数
  及主循环调用 (printf 重入修复后 SPI 写无罪已确诊, 实验收尾)
- loop_uart_proto.h/c: UART2 波特率注释 115200/19200 -> 192000
  (usart_biz.c 硬编码 192000 为实际值; g_storage_uart_baud=19200
  为独立配置项不驱动 UART2, BLE 显示 19200 不代表实际速率)
- devlog: 新增 2026-08-14 条目, UART2 RX DMA 方案列入待办
