wangfq 89ba602e4f fix(vd960DBN): 栈溢出修复闭环 — 打印恢复 + 字符串0终止保险 (2026-08-17) ...

RAM 瘦身后栈 1.9KB→~4.75KB (END 0x2000f834→0x2000ed3c 实测), printf 峰值安全:
- cfig_flash.c: 恢复 load_cfg 3 处调试 PRINT (magic mismatch×2 + Sub_Code)
- cfig_flash.c: 字符串 0 终止保险 (remote_addr/client_id/username/password/topic_pub/sub
  末字节强制 '\0', 防 Flash 字符串不足定长时 %s 越界打印)
- peripheral_main.c: 恢复 output_cfg_from_flash() (调试配置打印)
- 注释更新为修复闭环说明

设备实测: 无复位, MQTT 连 159.75.137.141:1883, BLE 广播正常
