Fix includes

Run misc-include-cleaner on the codebase and fix all the includes.

misc-include-cleaner gets some things wrong, so had edit those back to
previous.  It doesn't seem to like nlohmann or zone.hpp very much.

At some point in the future we could fix these, and get these enforced
at CI time.
