Pull Request Overview

This PR modifies the proxy runner to use a ConfigMap approach for configuration instead of command line arguments, implementing checksums for force redeployment of resources and updating tests to reflect the new changes.

Key changes:

• Replace individual CLI arguments with --from-configmap flag in proxy runner
• Add ConfigMap checksum support for tracking configuration changes and triggering redeployments
• Update operator to generate RunConfig ConfigMaps and use ConfigMap-based deployment
