Add Backend Support for HTML File Links

[mohamdlog]

Description:
Update the Flask server to include HTML files from the GCS bucket in the /list-folder-contents/<folder_name> endpoint response. The backend should recognize HTML files, generate public URLs for them, and include these in the response JSON.

Acceptance Criteria:

• Modify the process_gcs_directory function to detect HTML files and add them to the response.
• Ensure the response JSON includes a path attribute for HTML files containing the public URL.
• Make sure HTML files are categorized properly within the relevant monitor lists in the JSON response.

Reason:
Building out the backend first ensures the data is readily available and well-structured for the frontend. This approach helps reduce integration issues later and allows for easier testing and validation of the new functionality.

How to Test:

• Run the Flask server.
• Use Postman to send a POST request to http://localhost:5000/list-folder-contents/<folder_name>.
• Check the JSON response for HTML file details with a valid path.
• Test URLs by opening them in a browser to confirm accessibility.

Good Files to Look at for More Information:

• Our bucket contains batches that have HTML files. One example is 2024-10-21-11-27-28_Batch_2/.
• DroneWorld\backend\PythonClient\server\simulation_server.py.
