+/**
+ * Backs the admin OAuth2 client overview (App\Controller\OAuthClientAdminController) - listing every
+ * registered client (almost always RFC 7591 self-registered, see that controller's docblock) with how
+ * many currently-live access tokens each one holds, and permanently removing a client plus everything it
+ * was ever granted.
+ *
+ * Deliberately does NOT use League\Bundle\OAuth2ServerBundle\Service\CredentialsRevokerInterface's
+ * DoctrineCredentialsRevoker: it unconditionally also issues an UPDATE against the DeviceCode model/table,
+ * which does not exist in our schema (config/packages/league_oauth2_server.yaml disables the device code
+ * grant, so migrations/Version20260726180454.php never created oauth2_device_code) - that call would
+ * throw "no such table" here. The access/refresh tokens and authorization codes (the 3 credential types
+ * we actually persist) are bulk-deleted directly instead, before removing the client itself - the
+ * "client" FK columns are mapped ON DELETE CASCADE (see League's Persistence\Mapping\Driver), but SQLite
+ * only enforces that when "PRAGMA foreign_keys = ON" is set on the connection, which is not guaranteed
+ * here, so this does not rely on it.
