fix: ‘order’ should be translated to '订单' rather than ‘命令’ in Chinese

[unaheidi]

In Chinese, we use "订单" to express ’order for goods‘ rather than ’命令‘.
And when Chinese people use ’命令‘, we want to express ‘command’ .
So I suggest that 'order' in ecommerce should be translated to "订单" in Chinese.

Looks good to me. We might want to look at replacing other usages but we can do that in a separate ticket.
