fix(ui): properly passes readOnly prop to email & username auth fields (#9938)

### What?

The `readOnly` prop was not being passed down to the `email` &
`username` auth fields.

Resulting in these fields not being disabled properly if `update` access
was restricted.

### How?

Passes the `readOnly` prop through to the fields and now properly
disables these fields if `update` access is restricted.
