PR 2 of 3 from the user-menu chantier. * New lazy-loaded `/profile` route in `apps/portal-admin`. Renders the active admin session's identity card (displayName, username, oid, tid) plus an "App roles" card listing the Entra app-role claims attached to the session — `Portal.Admin` today, additional business roles when the strategic security baseline ADR lands. * `authGuard` (from `feature-auth`) gates the route — anonymous visitors bounce through the BFF's `/api/admin/auth/login`. The template's `@if (user())` then narrows the type so the page can drop the anonymous branch. * The `User Menu`'s Profile entry (PR 1) already points at `/profile` so the link starts working on this surface as soon as this lands. * `CurrentUser.roles` extended with an optional `readonly string[]` — the admin-side `/api/admin/auth/me` already returns the claim; the type now captures it. User-portal `/me` keeps omitting it per ADR-0009 (PR 3 surfaces it via the dedicated capabilities endpoint). * Lazy chunk lands at 5.37 KB raw / 1.57 KB gzip — comfortably under the lazy-chunk budget.
