Add a simple backend health check endpoint (/health)

[Aaravanand00]

Summary

Currently, there is no dedicated health check endpoint to verify that the Flask backend is running correctly.

Adding a lightweight /health endpoint would make it easier to:

• Verify backend availability
• Support deployment checks
• Integrate with CI or monitoring tools in the future

---

Proposed Improvement

Add a simple route:

@app.route("/health", methods=["GET"])
def health():
    return jsonify({
        "status": "ok"
    }), 200

Benefits

• Useful for development and debugging

• Helps validate server startup

• Future-ready for monitoring or deployment automation
