Fix Apify API errors messages and return them instead of the generic one

[MQ37]

{"time":"2025-09-04T14:27:38.468Z","level":"ERROR","msg":"Error calling actor","error":{"name":"ApifyApiError","message":"Monthly usage hard limit exceeded","stack":"ApifyApiError: Monthly usage hard limit exceeded\n

In the case above the generic "An error occurred while calling the tool." is returned instead of the Apify error mesage since the if (error instanceof ApifyApiError) { is not probably working correctly.
