/**
 * #5192 — Blocking the "Auto (Zero-Config)" provider in Security settings must
 * remove the built-in `auto/*` combos from the `/v1/models` listing.
 *
 * The catalog advertises the built-in `auto/*` combos (#4164 / #4235) at the top
 * of `/v1/models`, but that injection loop ignored `settings.blockedProviders`,
 * so checking "Auto (Zero-Config)" in Security → Blocked Providers had no effect:
 * the model picker still showed `auto/*` entries. Blocking the system provider id
 * `auto` (its id and alias are both "auto") must suppress the whole `auto/*` block.
