/**
 * PUT /api/admin/database-backup/config must reject a
 * database_backup_destination_path that resolves inside a publicly served
 * directory (GHSA-jw8m-43r2-jqrm class, #1365).
 *
 * Before #1365, database_backup_destination_path was silently ignored by
 * databaseBackupService.backup() (a destructuring bug always fell back to
 * the hardcoded /backup/database), so this setting being freely writable by
 * any backup.create holder — the built-in `admin` role has it without
 * settings.edit or backup.restore — was harmless. Making the setting
 * actually take effect reopens the exact exfiltration path GHSA-jw8m fixed
 * for the per-request override, through the persisted setting instead.
