Domain isolation: replace cross-domain imports with service calls
Replace direct Calendar, MarketPlace, and Post model queries with typed
service calls (services.blog, services.calendar, services.market,
services.cart). Blog registers all 4 services via domain_services_fn
with has() guards for composable deployment.

Key changes:
- app.py: use domain_services_fn instead of inline service registration
- admin routes: MarketPlace queries → services.market.marketplaces_for_container()
- entry_associations: CalendarEntryPost → services.calendar.entry_ids_for_content()
- markets service: Post query → services.blog.get_post_by_id/slug()
- posts_data, post routes: use calendar/market/cart services
- menu_items: glue imports → shared imports
