E2E Testcontainers integration suite

Closes gap-analysis v2 §7.8 (no E2E vs live Postgres / §10.8
(Testcontainers opt-in suite).

- tests/e2e/transactionLifecycle.e2e.test.ts — Postgres-backed E2E
  suite via @testcontainers/postgresql. Brings up a real postgres:15
  container, applies schema.sql (via pg simple-query protocol so $$
  function bodies survive) + migrations 002/003/004, wires the
  plans endpoints against it, and asserts:
    * POST /api/plans persists and reads back
    * eventBus.publish produces a hash-chained pair with verifyChain
      returning ok
    * idempotency_keys row insertion round-trips
- jest.e2e.config.js — dedicated config for tests/e2e/ with 120s
  timeout; default jest.config.js now ignores /e2e/ so `npm test`
  stays fast (<5s) and doesn't require Docker.
- package.json — adds 'npm run test:e2e' (sets RUN_E2E=1).
- devDependencies — testcontainers + @testcontainers/postgresql.
- Suite gates on `RUN_E2E=1`. Without it the describe block is
  skipped, so CI environments without Docker don't fail; a guard
  test asserts the skip invariant.
- .github/workflows/ci.yml — adds orchestrator-test (tsc + jest)
  and orchestrator-e2e (gated on the 'run-e2e' PR label or any
  push to main).
- Verification:
    npx tsc --noEmit              clean
    npm test (unit)               7 suites, 80/80 passing
    npm run test:e2e              1 suite, 4/4 passing (docker up)

- *
- * Covers:
- *   - HMAC default mode (back-compat) — round-trip sign/verify
- *   - JWS compact mode — valid signature, payload-tamper detection,
- *     signature-tamper detection
- *   - EIP-712 mode — round-trip via ethers wallet, tamper detection
- *   - Mode switching via EVENT_SIGNING_MODE + getEventSigner()
- *   - legacyHmac helper preserves the pre-PR-O signature shape
