Add Docker Compose support with 0.0.0.0 binding

[Copilot]

Containerize the app so it runs via docker compose up --build with all services accessible on 0.0.0.0.

New files

• Dockerfile — Multi-stage build (node:18-alpine). Single container runs both Next.js and Express via concurrently. Non-root user.
• docker-compose.yml — Ports bound to 0.0.0.0:3000 and 0.0.0.0:3001, SQLite persisted in a named volume.
• .dockerignore

Configuration changes to support containerized runtime

• prisma/schema.prisma — Switched from hardcoded file:./dev.db to env("DATABASE_URL") so the DB path is configurable (Docker volume at /app/data/dev.db vs local ./dev.db)
• next.config.js — Rewrite destinations now use NEXT_PUBLIC_API_URL env var instead of hardcoded localhost:3001
• server/index.ts — app.listen binds to HOST env (default 0.0.0.0). CORS origins configurable via CORS_ORIGINS comma-separated env var.
• server/routes/auth.ts — OAuth callback redirect always uses FRONTEND_URL env (previously only in production mode)
• .env.example — Documents HOST, DATABASE_URL, FRONTEND_URL, CORS_ORIGINS

Usage

cp .env.example .env   # fill in Google OAuth creds
docker compose up --build
# Frontend: http://0.0.0.0:3000
# Backend:  http://0.0.0.0:3001

All changes are backward-compatible — local npm run dev works as before when DATABASE_URL=file:./dev.db is set in .env.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• checkpoint.prisma.io

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
