Why is it okay to use "are" at the end of a statement?
I found a page here that talks about verbs at the end of indirect questions, but I am specifically looking for an answer about why "are" can be used at the end of a statement that is not an indirect question.
For example:
I won't do that no matter what the circumstances are.
She does not know who they are.
To possibly add a little more clarity to my question, why is it okay to say the sentences above but not okay to say:
She does not know who are they.
I won't do that no matter what are the circumstances.
I feel like there is a really simple grammar rule that I am missing that will make all of this make sense.

I found a similar question here that has an answer talking about "is" at the end of a sentence. One of the answers says that you can't use a verb directly after a "wh-" word (i.e. who, what, when...). That would make sense in explaining why we say "who they are" and not "who are they," but that doesn't work when I think about something like: "Where are the cookies?" [Edit: I read the answer again. The difference here has to do with the order of words in a question versus the order in a statement.]
Another similar question is here, but the answer focuses on question formats again. Another answer says:
The normal order is subject-verb-object. When there is no object, the verb comes last in the sentence...
Then they give the example, "I don't know where the bank is." But "bank" is an object. So doesn't that mean we should technically say, "I don't know where is the bank" to follow the subject-verb-object order?
Both of the questions were sort of old so I decided to ask a new one.
Thanks for any help.
