refactor: update IP query API and response handling

- Switched from ip-api.com to ipinfo.io for IP information retrieval, ensuring more reliable service.
- Simplified response handling by directly using the data returned from ipinfo.io, eliminating unnecessary data transformation.
- Adjusted risk level determination logic to utilize the 'org' field for identifying potential hosting or datacenter IPs.
