Fix Shopware Docker build: add Redis support and align network includes

- Added symfony/redis-messenger installation with ignored build-time PHP extension checks
- Installed php83-redis in runtime stage
- Ensured consistent network includes across all Shopware services in docker-compose template
- Improves compatibility with Redis-based Symfony Messenger transport during init phase
