The goal of this task is to refactor the current code that fetches data from SonataFlow and use the "@kie-tools/runtime-tools-gateway-api" package to establish such communication.

The following webapps are already using "@kie-tools/runtime-tools-gateway-api" and can be used as references:

• https://github.com/kiegroup/kie-tools/tree/main/packages/sonataflow-deployment-webapp
• https://github.com/kiegroup/kie-tools/tree/main/packages/serverless-logic-web-tools
