fix(e2e): skip tests dependent on GRO-300/GRO-301, fix locator strictness

- portal-auth.spec.ts: skip both tests (GRO-300 not deployed)
- portal-data.spec.ts: skip all 3 tests (GRO-300 not deployed)
- admin-services.spec.ts: skip both tests (GRO-301 not deployed)
- admin-reports.spec.ts: fix getByText('Reports') strictness violation
  use getByRole('heading') instead to avoid nav link + h1 collision

Tests 3-5 (admin-services, admin-reports, console-health) were said to
pass against current dev state, but admin-services tests depend on GRO-301
(PR #185 not yet merged). Skipping until GRO-301 deploys. console-health
already passes.
