Consider Passing Format And Dark Mode Into Interactive Elements And Atoms

[JamieB-gu]

There are two ways of introducing interactive content into non-interactive articles:

1. Interactive atoms
2. Interactive elements

For 1) we already pass information about whether dark mode is supported as of #10298. There has been a suggestion from the Visuals team that it might be useful to also do something like this for 2). An additional suggestion was that we may want to pass ArticleFormat into both 1) and 2), so other variations of article design (like the backgrounds on analysis¹ and comment² pieces) could be handled.
