chore(deps): update @angular/cdk 21.1.5 -> 22.0.6

Ran via ng update @angular/cdk@22 - no code migrations required.

Verified after full upgrade (core/cli/animations/common/compiler/
forms/platform-browser/router/service-worker/cdk all now 22.0.8/
22.0.6): tsc --noEmit clean, ng build --configuration=production
clean (same pre-existing bundle-budget warning, size unchanged),
arch:check:boundaries and arch:check:cycles both pass. Live-verified
in browser: storefront home renders correctly (categories/products/
i18n all working), /backoffice/dashboard (admin shell, lazy-loaded
per the earlier routing fix) renders correctly, no console errors on
either.

Required a Node.js upgrade on the dev machine first (Angular 22 CLI
needs Node >=22.22.3 or >=24.15; machine had v22.16.0) - done by the
user before this update ran.
