Optimize CI and update docs for context fetch

Refined CI workflow by correcting npm cache permissions, ensuring smooth
dependency installation, and removing redundant Node.js update step to
enhance build speed and reliability. Furthermore, augmented
documentation in the UI component to clarify the retrieval and expected
presence of the Resources widget within the EthicalScannerApp context,
enforcing the widget's availability and preventing runtime errors.
