Describe the bug Prevent the selection of the user's table for forms within the design screens. Or prevent the ability from being able to save changes to the users table in the backend via the update forms.

To Reproduce Steps to reproduce the behavior:

1. Create a new app
2. Add a form block with the users table as the selection
3. Change the form from create to update
4. Add the current user _id binding to the form
5. Click preview
6. Amend some details
7. See that the user table is updated.

Expected behavior Either you shouldn't be able to add the users table as a form option, or the backend should error out saying you can't edit this table.
