* Add Backend Logic for Toggling Email Notification

This commit adds the backend logic for
allowing users to enable or disable email
notifications. The implementation ensures
that only issue notification emails get disabled
and important emails are still sent regardless
of the setting.

The UI to toggle this setting has not yet been
implemented.

* Add UI and complete user email notification enable

This commit completes the functionality to allow
users to disable their own email notifications.
