feat: Add hello endpoint to root URL

Related Issue(s):

Closes #1

What does this MR do?

Adds a simple "hello" endpoint at the root URL (/) that returns a basic HTTP response with the text "hello". This implements a minimal homepage functionality for the Django project.

Why was this MR needed?

The project previously had no content at the root URL, which would result in a 404 error for users visiting the base site. This change provides a basic landing page response.

How was it implemented?

• Added a simple hello view function in myproject/urls.py that returns an HttpResponse with "hello" text
• Configured URL routing to map the root path ('') to the new hello view
• Used inline function definition for simplicity given the minimal functionality

How to test:

1. Run the server: python manage.py runserver
2. Visit root URL: Navigate to http://localhost:8000/
3. Verify response: Should see "hello" text displayed in browser
4. Admin still works: Confirm http://localhost:8000/admin/ still functions normally
