WIP checkpoint: Scaffold FastAPI backend project structure

Scaffolding only — FastAPI app, SQLAlchemy models, Alembic migrations,
and docker-compose from the original task description are still not
implemented. Committing what exists so it isn't lost; task ec0074121ca3
reset to pending to finish the rest.
