Add typed service contracts (Protocols + frozen DTOs) in shared/contracts/
for cross-domain communication. Each domain exposes a service interface
(BlogService, CalendarService, MarketService, CartService) backed by SQL
implementations in shared/services/. A singleton registry with has() guards
enables composable startup — apps register their own domain service and
stubs for absent domains.
Absorbs glue layer: navigation, relationships, event handlers (login,
container, order) now live in shared/ with has()-guarded service calls.
Factory gains domain_services_fn parameter for per-app service registration.

- Templates: item.post.X → item.X (MenuNode has label/slug/feature_image directly)
- factory.py: add glue.models to import loop + register_glue_handlers() at startup
- alembic env.py: add glue.models to import loop
- New migration: container_relations + menu_nodes tables with backfill from existing data

Cross-domain relationships like Product.order_items → OrderItem use
string references that SQLAlchemy resolves by class name lookup. All
model packages must be imported so every class is registered before
mapper configuration runs.

shared/logging/ shadows Python's stdlib logging module, causing a
circular import when any code does `import logging`. This breaks
both the entrypoint Redis flush and Hypercorn app loading.
