Add debugging step to deploy-staging.yml to verify directory structure

- Added a step to list the root directory contents in the GitHub Actions workflow to verify that the client directory and necessary files are accessible.
- Ensures that the workflow can locate client/public/index.html and other essential files during the build process.
- This update helps identify issues with directory paths and confirms the presence of required files in the GitHub Actions environment.

This change aims to resolve build issues by providing more insight into the directory structure during deployment.
