"""Saving prefs with auth disabled must not wipe a multi-user store.

When auth is disabled get_current_user returns None. _save_for_user(None,...)
|
|
wrote prefs flat, overwriting the entire {"_users": {...}} map and destroying
|
|
every other user's preferences (a realistic ops transition: auth turned off
|
|
on a deployment that previously ran multi-user). It must preserve the other
|
|
users and round-trip the change into the same (first) slot _load_for_user

reads from.
