* fix: downcase email when finding
* feat: add `from_email` class
* refactor: use `from_email`
* feat: add rule to disallow find_by email directly
* chore: remove redundant test
Since the previous imlpmentation didn't do a case-insentive search, a new user would be created, and the error would be raised at the DB layer. With the new changes, this test case is redundant
* refactor: use from_email
- We have observed some failures for data import jobs in the cloud due to race conditions with job executions and active storage file uploading. This PR adds delays and retries to accommodate that.
- Ensure existing contact information is updated on data import
- Refactor the existing job to make it more readable
- Fixes issues with import files in the wrong encoding
fixes: #7307
When we migrated the pubsub tokens from contact to contact inboxes, we missed out on doing this update for the typing indicator events. Hence the agent typing events weren't visible on the widget side. This change fixes that and removes the necessary column contact pubsub token from the model.
fixes: #4476
