feat: allow DependentResourceNode creation override

[xstefank]

We want to provide CDI beans in the Condition subclasses as requested in quarkiverse/quarkus-operator-sdk#720.

[Copilot]

Pull Request Overview

This PR enables CDI bean injection in Condition subclasses by making DependentResourceNode creation configurable through the DependentResourceFactory. This allows frameworks like Quarkus to override node creation and inject dependencies into conditions.

• Made DependentResourceNode class public for external extensibility
• Replaced direct node construction with factory method delegation
• Added default createNodeFrom method to DependentResourceFactory interface
