feat(app): Next.js 15 + Auth.js v5 portal skeleton
Lands the minimum surface so a developer can:

  cd platform/orca-platform && make dev-up
  cd platform/tenant-registry && make dev
  cd platform/portal && make install && make dev
  open http://acme.localhost:3000

and complete a real OIDC sign-in against the breakpilot-dev realm.

Layout:
  src/middleware.ts                host→slug URL rewrite; backstage carve-out
  src/auth.ts                      Auth.js v5 Keycloak provider; passes
                                   tenant_id/slug/org_roles/products/plan/status
                                   claims through to the session
  src/app/api/auth/[...nextauth]/  Auth.js handlers (GET, POST)
  src/app/layout.tsx               root html shell
  src/app/page.tsx                 apex landing
  src/app/[slug]/layout.tsx        fetches tenant via lib/tenant-registry
  src/app/[slug]/page.tsx          redirect to /dashboard
  src/app/[slug]/dashboard/page.tsx
                                   signed-out → Sign in with Keycloak
                                   signed-in  → welcome + Sign out
  src/lib/host.ts                  testable host parser (apex/tenant/backstage)
  src/lib/tenant-registry.ts       fetch client for the Go service

Tooling:
  vitest                           13 tests, 100% coverage of src/lib/
  Next.js 15 build                 compiles all routes; output: standalone
  ESLint flat config               next/core-web-vitals + next/typescript

Real RBAC enforcement, the rest of the customer-area surfaces, and the
backstage shell land per the M5.2 / M10.1 schedule. This is just enough
to be the first thing a developer codes in.

// Auth.js v5 — Keycloak provider.
//
// Dev uses the breakpilot-dev realm from platform/orca-platform/dev. The
// realm's dev-portal client is a public PKCE client; we still pass a
// non-empty clientSecret because the Keycloak provider requires it
// structurally — it's unused in the auth code grant for public clients
// when PKCE is enabled.
