Tim Abbott 85222b790d edit_history: Refactor to use FormattedEditHistoryEvent type.
We fix the mutation of caller and other bad patterns, as well as
adding explicit typing to make the code readable.

We also update the OpenAPI documentation for previously
undocumented `prev_strem` field in the `/get-message-history`
endpoint for API validation testing.

"""In most API endpoints, we use a default value of `None"` to encode
parameters that the client did not pass, which is nicely Pythonic.
However, that design does not work for those few endpoints where
we want to allow clients to pass an explicit `null` (which
JSON-decodes to `None`).
We use this type as an explicit sentinel value for such endpoints.

currently an internal implementation detail of the REQ class?
