dde-fite/42_Fly_in ? reverse-engineered prompt

Build me this Fly_in project into a working app.

I want a web app for simulating drone traffic from a text map file, where a user can upload a map, see the simulation, and step through the drone movements turn by turn. The backend should parse the map, create the simulation, generate the drone routes, and expose the API for token creation, simulation creation, stepping, and reading hubs, drones, connections, and itineraries. The frontend should let me upload a file, start a simulation, and display the results in a clean way, ideally with the turn by turn progress visible.

Please make the whole thing run as a monorepo with the backend and frontend working together, and keep the session token flow in place so each simulation is tied to a token. If anything is missing or unclear, use the README as the guide and look up current docs online if you need to. I’d like it to be runnable locally with a simple command and include whatever setup is needed to test it quickly.
