Implements dynamic retrieval of Lenovo PSREF API token

Browse Source 
Adds a new function to programmatically retrieve the required authentication token for the Lenovo PSREF API. This change is necessary as Lenovo is now restricting API access without a JavaScript-generated token.

The new function launches a headless browser instance, uses the DevTools protocol to extract the token from local storage, and then terminates the browser. This ensures continued access to the comprehensive model data available through the PSREF API, which is not fully present in other catalogs.

The User-Agent string has also been updated.
