Chaim 94bc66d7c1 Bundle FastAPI backend into Next.js Docker container
The Next.js app was proxying /api/* to the old Flask/FastAPI server
at legal-ai.nautilus.marcusgroup.org. When that server went down,
the Next.js app's API calls failed with 503.

Now both services run in the same container:
- FastAPI (uvicorn) on :8000 — the API backend
- Next.js (node) on :3000 — proxies /api/* to localhost:8000

Changes:
- Dockerfile: multi-stage build with Python 3.12 + Node.js
- next.config.ts: default proxy target is now 127.0.0.1:8000
- start.sh: launches uvicorn in background + node in foreground
- pyproject.toml: add fastapi + uvicorn as explicit deps

# Dockerfile — Next.js frontend + FastAPI backend (single container)
#
# The container runs both:
# - FastAPI (uvicorn) on :8000 — the API backend
# - Next.js (node) on :3000 — the frontend (proxies /api/* to :8000)
#
# start.sh launches both processes.
