Brings full Postgres + api + web compose setup so the app can run on any
machine with just Docker, instead of requiring a host PostgreSQL install.
Includes a one-shot migrate service that pushes the Drizzle schema before
the API starts. Web image serves the Vite build via nginx and proxies
/api/* to the api-server.
