feat(dashboard+ci): close DASH-04/06/07, add login route, wire CI for pilot + dashboard tests

Dashboard security — all 8 findings now resolved (was 5/8):
- DASH-04: app/api/risk/scores returns synthetic:true + DEMO disclaimer so mock
  series can't be mistaken for an SR 11-7 model output.
- DASH-06: next.config.js sets CSP + X-Content-Type-Options/X-Frame-Options/
  Referrer-Policy/Permissions-Policy/HSTS; middleware.ts + lib/http/rateLimit.ts
  add per-client rate limiting (120 req/min) on /api/*.
- DASH-07: consentLedger.ts signs each event hash (HMAC stand-in for the
  Dilithium/ML-DSA HSM signer), verifies the chain on export, and FAILS CLOSED on
  prevHash read errors (no silent new chain). Also fixed pre-existing invalid
  'catch (e: Error)' TypeScript in this file.
- Added app/api/auth/login/route.ts: demo login issuing a signed, HttpOnly,
  SameSite=Strict sentinel_session cookie via mintToken (real IdP/OIDC in prod).
- Tests extended to assert the fixes: vitest 19/19 pass (16 security + 3 gov).
  New/modified files typecheck clean (0 TS errors).

CI (.github/workflows/runnable-assurance.yml):
- Install solc (contracts) so assurance steps 7 (zk relayer) + 10 (contract
  compile) actually run in CI; install Terraform 1.9.8 for the pilot IaC gate.
- Add contract-logic pytest to unit tests.
- Add '2028 pilot acceptance-gate checklist' step (6/6 automated gates).
- Add separate 'dashboard-tests' job running next-app vitest.
- Trigger on governance_blueprint/** and next-app/** too.

Regression: run_runnable_assurance.sh 11/11 PASS; pilot 6/6 automated; vitest 19/19.
