Fix cookie defaults on the bootstrapped workspace and tie order in ordered atoms

`Workspace::default()` is derived, so the first workspace was created with
`setting_send_cookies` and `setting_store_cookies` false, contradicting the
model's `default_true` serde defaults and the migration's DEFAULT TRUE.

`createOrderedModelAtom` returned -1 for equal keys, an inconsistent
comparator, so same-millisecond `http_response_event` rows came out of
V8's sort reversed.
