Fix: resolve FastAPI backend startup issue caused by ASGI import error

closes #257

📝 Description

This change fixes a backend startup issue where Uvicorn failed to load the FastAPI ASGI application due to an incorrect or inaccessible module import.

The fix ensures that the FastAPI entry point is properly defined and that the ASGI app instance can be discovered by Uvicorn.

---

Before

• Running the following command:

  uvicorn main:app --reload
  

resulted in:
ERROR: Error loading ASGI app. Could not import module "main".

After:

• Running the following command:

  uvicorn app.main:app --reload
  
  

• The FastAPI entry point is correctly defined and importable
• Uvicorn starts successfully with hot reload enabled
• Backend server is accessible at:
  http://127.0.0.1:8000

---

Reason for Change

Uvicorn requires the following to run a FastAPI application correctly:

• A valid Python module path
• An exposed ASGI app instance

This fix ensures proper ASGI app discovery, prevents startup-time import errors, and restores a stable local development workflow.

Summary by CodeRabbit

• Documentation
  • Updated backend startup instructions in the README with the correct module path reference for running the application.

🐰 A path was lost, now it is found,
The module route now quite sound,
From main to app.main we hop,
The startup command's back on top! 🚀

128-131: Working directory mismatch: Setup instructions place users in the wrong directory for the server startup command.

The backend setup instructions direct users to navigate into the app subdirectory (step 3: cd app), placing them in backend/app/. However, the startup command on line 178 (uvicorn app.main:app --reload) requires the module path app.main, which only resolves correctly when running from the backend/ directory. When executed from backend/app/, the command attempts to import from backend/app/app/main.py, which doesn't exist.

Fix this by either:

1. Removing the cd app step from the backend setup instructions so users remain in backend/ when starting the server, OR
2. Updating the startup command to uvicorn main:app --reload if users should stay in backend/app/ after setup.

There is no such command as the one suggested above as I tested it locally. The backend runs correctly using the command already mentioned in the documentation (uvicorn main:app --reload).
