/**
 * DEPRECATED / LEGACY
 *
 * This standalone script is no longer the recommended way to query offline devices.
 *
 * Use the Webex bot command instead:
 *   In your Webex space: type `offline` (or `offline some-filter`)
 *
 * The main server (index.js) now provides a much better implementation:
 *   - Uses the Appspace refresh token flow (not static APPSPACE_API_TOKEN)
 *   - Shares token management with the webhook path
 *   - Has filtering, better table output, and MDM enrichment in other flows
 *
 * This file is kept only for emergency/audit use. It uses older env var conventions
 * (APPSPACE_BASE_URL + APPSPACE_API_TOKEN) and performs a one-shot query then exits.
 *
 * Consider removing this file once the bot command has been validated in production.
