[native][web] Remove processing the ops from reducers

Summary:
We no longer need to process the ops in reducers because the new handler handles that.

https://linear.app/comm/issue/ENG-7099/stop-processing-the-ops-in-master-reducers

Depends on D11367

Test Plan: Check if the changes are persisted in the db - by e.g. checking if the drafts remain present after restarting the app.
