Add directory listing for client/public in deploy-staging.yml for debugging

- Added a step to list the contents of client/public in the GitHub Actions workflow to confirm accessibility of necessary files.
- Also included root directory listing to check the overall project structure during workflow execution.
- This update helps identify any issues with file paths or missing files, ensuring that the build process can locate index.html and other required files.

This change aims to resolve build errors by providing clearer insights into the directory structure within the GitHub Actions environment.
