Move "Calendar" above "Badges" on user profiles

Summary:
Ref T11809. As we move toward unprototyping, this panel is probably more relevant/dynamic/interesting more often than the badges panel, I think?

Particularly, I want to make the red dots a little easier to understand, and I think putting this above the fold will help aid discovery (red dot -> click -> see red dot -> see "away until ..." -> see calendar -> "oh they're at a meeting"?).

This is entirely a product/subjective thing so I'm fine with not doing it or using a different order.

I think there's maybe even an argument for putting this above "Projects", but "Projects" feels more core to me, at least for now.

Test Plan: Viewed a user profile, saw "Calendar" above "Badges".
