MVP 0.2 Backend Setup API + Data Flow

[Boxuan-Matty-Lin]

Background

The backend repository has been bootstrapped (uv + FastAPI) and CI is already in place with Ruff linting and formatting. The next step is to implement the backend MVP APIs to support frontend integration and complete the core end-to-end flow.

Goals (MVP Scope)

• Provide the minimum set of APIs: health, menu, and orders
• Use PostgreSQL to support the end-to-end flow: create an order and fetch an order
• Ensure /docs (OpenAPI) is available so the frontend can integrate smoothly

This GitHub issue outlines the next steps for setting up the backend MVP (Minimum Viable Product) to enable integration with the frontend and complete the core end-to-end flow. The backend repository is already established using uvicorn and FastAPI, with CI configured for code linting and formatting via Ruff. The MVP scope includes implementing essential APIs (health, menu, and orders), integrating PostgreSQL to enable creating orders and fetching them, and ensuring OpenAPI documentation (/docs) is accessible for seamless frontend integration.
