docs: sync Docker Compose section across all language READMEs

Apply the same updates as the English/Chinese READMEs:
- Use docker compose -f docker/docker-compose.yml for all commands
- Update setup flow to first-run auto-config pattern
- Replace build/rebuild section with update via docker pull
- Affected: README.fr.md, README.ja.md, README.pt-br.md, README.vi.md
