- Fix AdminLayoutComponent.readRouteData crash: leaf route snapshot/data is now optional with dashboard-title fallback, so admin deep links never crash the shell when route metadata is missing (root cause of every blocked browser test since Sprint 12)
- Never-settling promises fixed: all gateway ensureData() bridges (products, categories, moderation) and the catalog category resolver now resolve with an empty list on transport failure instead of hanging forever, so API outages surface as empty states with guidance rather than permanent skeletons plus global console errors
- Request de-duplication: BackofficeDataService caches products/categories with shareReplay - one in-flight request per endpoint shared by all consuming gateways (was 5+ duplicate requests per admin page load); failures clear the cache so the next call retries
- Gateway contract audit: all 8 admin gateways (products, categories, orders, customers/moderation, transactions, users, dashboard metrics, monitoring) now implement an explicit *Gateway interface - added the missing AdminMonitoringGateway; media already swaps via the abstract MediaRepository DI class
- Mock mode untouched: provider selection still flows through RuntimeProviderStrategyService/BACKOFFICE_DATA_PROVIDER
Sprint 2 high-priority cleanup: layout preference read/write called raw
localStorage from a component, violating the no-raw-localStorage rule.
Now uses the shared core/storage/LocalStorageService (same as
cart/language/location services).

Unify product details modules behind config-driven contracts so teams can
extend UX without changing runtime architecture or bootstrap flow.
Keep backward compatibility with existing product payloads by treating new
media/specification/variant/related structures as optional extensions.
Improve conversion and content discoverability with reusable actions,
typed media rendering, grouped specifications, dynamic variants, and
multi-collection related products.
