PageConfig (db_blog) decoupling: - Blog: add page-config, page-config-by-id, page-configs-batch data endpoints - Blog: add update-page-config action endpoint for events payment admin - Cart: hydrate_page, resolve_page_config, get_cart_grouped_by_page all fetch PageConfig from blog via HTTP instead of direct DB query - Cart: check_sumup_status auto-fetches page_config from blog when needed - Events: payment routes read/write PageConfig via blog HTTP endpoints - Order model: remove cross-domain page_config ORM relationship (keep column) Cart + Market DB merge: - Cart tables (cart_items, orders, order_items) moved into db_market - Cart app DATABASE_URL now points to db_market (same bounded context) - CartItem.product / CartItem.market_place relationships work again (same database, no cross-domain join issues) - Updated split-databases.sh, init-databases.sql, docker-compose.yml Ghost sync fix: - Wrap PostAuthor/PostTag delete+re-add in no_autoflush block - Use synchronize_session="fetch" to keep identity map consistent - Prevents query-invoked autoflush IntegrityError on composite PK Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
