feat(shopware): migrate to single Shopware base image and split services (web/worker/scheduler/init)

• Introduce init container and runtime-ready Dockerfile (Alpine) installing php83-gd/intl/pdo_mysql
• Disable composer scripts in builder and ignore build-time ext reqs
• New docker-compose template (web/worker/scheduler/opensearch) + persistent volumes
• Use TRUSTED_PROXIES env; fix APP_URL formatting; set OPENSEARCH_HOST=opensearch
• Replace SHOPWARE_PHP_CONTAINER refs with SHOPWARE_WEB_CONTAINER in tasks
• Render and copy init.sh via volumes path
• Remove old nginx/php split and legacy DB env task
• Fix svc-db-postgres var: database_type now uses entity_name
