Upgrade kea format from v2 to v3

We're using a library called Kea for state management. The library has a concept called "logics" and their format got changed in the upgrade to version 3. While the old format still works, it would be great to have all logics converted to the new format for consistency eventually.

You can find logics still in the old format by searching for import { kea } from 'kea'. The newer format imports other bits from kea as well, which is why this will find logics in the old format.
