Read copy_slots source data from cache, not a live query

get_users()/get_credentials() (fresh) walk the device's linked list of
users via nextUserId, so a slot the firmware didn't chain in correctly
(e.g. slot 250 on a real lock, confirmed via zwave-js's AccessControl.ts)
gets silently missed. get_users_cached()/get_credentials_cached() scan
every ID up to the reported max instead, matching what the slots sensor
already relies on and catching such orphaned entries.
