Remove nginx/webapp container; single Go server serves SPA + API

- Add root Dockerfile: node build → copy dist into Go embed path → distroless binary
- Update docker-compose: one service (api on :9050), DB renamed ralph→pamietnik
- Remove references to RALPH/reisejournal across all docs and configs
