fix(portal-shell): send withCredentials on /me so the session cookie crosses SPA→BFF in dev (#114)
## Summary

Manual smoke after PR #113 surfaced a dev-only bug: after `/auth/callback` the BFF correctly sets the `portal_session` cookie and redirects to the SPA, but the SPA's next call to `/api/auth/me` comes back **401 with no `cookie:` header at all**. The user lands "back at the portal" but the header still shows "Sign in".

**Root cause.** Angular's `HttpClient` via `withFetch()` inherits `fetch`'s default `credentials: 'same-origin'`. In dev, `localhost:4200` (SPA) → `localhost:3000` (BFF) is cross-origin (different ports), so the browser drops the session cookie on the way out. SameSite=Lax is a red herring: both URLs share the registrable domain, so the cookie is still same-site — what was missing was opting the fetch into credentials.

**Fix.** Per-call `withCredentials: true` on the /me request. Only /me needs cookies today; login/logout are full-page navigations through `window.location`, which the browser hydrates with cookies regardless. A global `HttpInterceptor` will be the right abstraction once other authenticated BFF endpoints exist — premature for one consumer.

**BFF side was already correct.** `enableCors({ credentials: true })` in `main.ts`. Nothing to change.

A new spec pins `withCredentials === true` on the /me request so a future refactor can't silently drop the flag and reintroduce the bug.

## Test plan

- [x] `pnpm nx test feature-auth` → **9/9 pass** (was 8 before; +1 spec pinning the credentials flag).
- [x] `pnpm nx test portal-shell` → **32/32 pass**.
- [x] `pnpm nx lint feature-auth portal-shell` → clean.
- [x] `pnpm nx build portal-shell` → clean.
- [ ] Manual smoke against the running BFF: anonymous landing → click "Sign in" → Entra → callback → SPA lands with avatar + display name in the header (the very last step that failed before this fix).

Documentation index

This is the entry point to all project documentation. It is maintained automatically: any addition, rename, or removal of a .md file under docs/ must be reflected here in the same change.

Conventions

  • Documentation is written in English.
  • One topic per file. Group related files into a folder when there are three or more.
  • Cross-reference with relative links so they keep working in GitHub, IDEs, and exported sites.
  • For architectural decisions, do not add them here — they belong in decisions/ as MADR 4.0.0 ADRs.

Sections

Daily development

  • development.md — repo layout, prerequisites, initial setup, daily commands, observability dev-loop (Jaeger UI, log ↔ trace correlation), dependency updates (Renovate), conventional commit cycle. Day-to-day reference for working on the project.

Architecture

  • architecture.md — cross-cutting Mermaid diagrams: C4 system context, C4 containers, Nx module boundaries, CI/CD pipeline. Single-decision diagrams (auth sequence, ERD, etc.) live inline in their ADR.

Onboarding & environment

Setup guides for new contributors:

Operations & runbooks

Security, performance, accessibility

Empty — placeholders to be filled with rationale docs alongside their corresponding ADRs.
