core/identity (Customer/ExternalIdentity/ContactChannel models + VkIdGateway/
token/mock) and a standalone VkIdLoginComponent, per Sprint 0.1's "VK ID
first" decision and v3.1 §14. Against
docs/backend/PHASE-8-IDENTITY-MESSAGING-CONTRACT.md §1-2.
Deliberately not wired into TelegramLoginComponent's dialog - that's the
live, working QR-login surface for both customer and admin auth
(components/telegram-login/), and splicing a second provider into it
needs a real VK OAuth app to test against, not a mock bolt-on next to
nine other phases. The button is a standalone, ready-to-place component;
integrating it into checkout/login flows is follow-up work once VK
credentials exist.
