feat: Docker self-hosting setup with migration service and auth bypass

- Fix Dockerfiles to copy pnpm-lock.yaml (frozen-lockfile compliance)
- Add migrate target to API Dockerfile using builder stage
- Add migrate service to docker-compose that runs before API starts
- Add AUTH_DISABLED env var bypass to auth middleware for dev/Docker
- Proxy /api/ from nginx to API container (no CORS needed)
- Include initial Drizzle migration (0000_colossal_colossus.sql)
- Add .env.example with all configurable variables
- Update README with Docker self-hosting instructions

Closes #7
