DOCS UPDATE: Incorrect Flask command path in backend installation guide

Open docs/INSTALL_GUIDE.md and review the Quick Start section, specifically Step 8 for starting the backend server. Verify the working directory and Flask command against the path described in the issue; done means the guide no longer gives the incorrect path and can start the code-graph backend as documented.

📌 Current Documentation Issue

In the Installation Guide → Quick Start → Step 8 (Start the backend server), the documentation instructs users to run the following command from the backend directory:

flask --app api/index.py run --debug --port 5000

However, this command fails when executed from the backend/ directory because the Flask application file (index.py) is not located at backend/api/index.py. The actual Flask app is located at:

backend/app/database/falkor/code-graph-backend/api/index.py

As a result, running the command exactly as written leads to the error:

Error: Could not import 'index'

This can be confusing for new contributors, especially on Windows.

✨ Proposed Changes

Update Step 8 of the installation guide to reflect the correct working directory and Flask app path.

Suggested corrected instructions:

# Terminal 3 (Start graphDB / Code Graph Backend)
cd app/database/falkor/code-graph-backend
flask --app api.index run --debug --port 5000

Optionally, the guide could also mention that:
The Flask command must be run from the code-graph-backend directory

This change would make the setup instructions accurate and reduce onboarding friction.

📋 Additional Context

This issue was encountered during a fresh local setup following the installation guide step-by-step.
The rest of the backend (FastAPI, Docker services, Discord bot) works as expected once this path issue is resolved.
