Set type="password" on all auth_token fields (#22175)

Set `type="password"` on all `auth_token` fields

Seen when migrating from other hosting platforms.

1. Prevents exposing the token to screen capture/cameras/eyeballs.
2. Prevents the browser from saving the value in its autocomplete
dictionary, which often is not secure.
