feat: first client onboarding — fix env, add loyalty admin, dev infra-check

- Fix .env: wizamart→orion/wizard.lu, Redis port→6380
- Fix .env.example: orion.lu→wizard.lu domain references
- Add create_loyalty_admin() to init_production.py (platform-scoped admin for rewardflow.lu)
- Add `make infra-check` target running verify-server.sh
- Split verify-server.sh into dev/prod modes (auto-detected from DEBUG flag)
- Dev checks: .env config, PostgreSQL, Redis, health endpoint, migrations
- Remove stale init.sql volume mount from docker-compose.yml
