wangfq 0b51d84a9b perf(vd960DBN): OTA RAM 优化 — union 复用块缓冲 + 命令分支数组改 static ...

MRS 编译 RAM 90.02% (44248/48KB) 逼近历史 .bss 挤栈红线, 减负:
- ota_srv.c: _chunk_buf[256] + _fs_frame[254] 合并为 union (下载/校验与刷写帧
  互斥复用, 省 ~260B static); ota_send_9f 组帧直接用 union 缓冲 (省 254B 栈)
- iot_mqtt_srv.c: 6 个 ota_* 分支 resp[256~400] + ota_data hexbuf[513] 局部栈
  数组改 static (栈峰值 → BSS, 防运行时栈溢出; RAM 总量不变但运行时安全)

验证: gcc 隔离单测 9/9 全过; 语法 0 新增错误
