Add Docker packaging (Dockerfile, compose, sidecar deps)

- Dockerfile: node:22-bookworm-slim + Python venv with trimesh for the
  3MF->GLB sidecar (PYTHON_BIN env points the converter at it)
- docker-compose.yml: app + postgres 16 with healthcheck/depends_on,
  named volumes for pgdata/uploads/thumbnails/glb, token env passthrough
- .dockerignore, tools/requirements.txt
- converter.js honours PYTHON_BIN (defaults to local venv)
