Add production Dockerfiles and the Compose stack with dev overlay

Multi-stage images: web (workspace build baked into unprivileged
nginx with SPA fallback, asset caching, /healthz) and api (pnpm deploy
bundle with the prisma CLI for migrate-on-start, non-root, node-based
healthcheck). deploy/compose/docker-compose.yml defines the stage
stack (web, api, db) with frontend/internal networks, localhost-only
published ports for the host reverse proxy, log rotation, and named
volumes; .env.example documents every variable. compose.dev.yml layers
hot-reloading dev containers (or database-only usage) over the same
definition. Verified locally: full stack healthy, SPA fallback, readyz
green after automatic migration, db not reachable from outside.

Closes #6
