Dockerize TaskFlow Frontend & Backend Lab

In this hands-on lab, you'll containerize both tiers of the TaskFlow reference application you set up in Week 5. You'll create a multi-stage Dockerfile for the Vue.js frontend (build with Node, serve with Nginx) and a Python Dockerfile for the FastAPI backend with health checks.

This is your first time containerizing a real application, and you'll see how Docker makes deployment consistent across environments. You'll also write actual Python code to add a health check endpoint to the backend API.
