/**
 * Admin login uses the exact same Telegram QR/session API as the customer
 * login (TelegramSessionApiService) - there is no separate admin backend
 * endpoint, and none should be invented client-side. Only the *storage* is
 * kept separate from AuthService, so an admin QR scan never authenticates
 * the customer session or vice versa: distinct cookie name, distinct
 * signals, distinct guard/interceptor.
 *
 * Since the session API itself has no concept of "admin", the frontend
 * cannot tell an admin Telegram session from a regular one. Actual admin
 * authorization must be enforced server-side when admin API calls are made
 * with the resulting session id - the frontend only decides where to
 * *store* the result.
