Split this into two documents: "Special variables" and "Constants". "Special variables" should go just after "Built-in query lang functions" in the sidebar.

I think the article we really want is "Built-in query language constants" that is analogous to the "Built-in query language functions" that we already have.
This "Constants" article is not that. This article refers to the deephaven.constants module. This is concerning because if the user does something like from deephaven.constants import NULL_DOUBLE, they will have the python value in their namespace and would use it in a query. That would result in a very slow query. I suggest removing any articles on deephaven.constants or rewriting them to be very clear on how to use them safely and efficiently.
Our Auto-imported functions article is really Auto-imported functions and constants. It should be retitled and have the prose slightly modified to indicate that the constants are listed as well.
If we do create a "Built-in query language constants" article, it should go immediately before the equivalent functions article.
