PR Z: sandbox deployment scaffolding (deploy script + Dockerfiles + compose)

- contracts/scripts/deploy-notary-registry.ts: self-compiling ethers v6
  deploy for NotaryRegistry.sol (solc-js in-process — avoids hardhat's
  HH1006 on contracts/node_modules), with NOTARY_DRY_RUN mode and a
  machine-readable JSON envelope as last stdout line.
- contracts/hardhat.config.ts: chain138 network (RPC defaults to the
  public endpoint that resolves EXT-CHAIN138-CI-RPC).
- orchestrator/Dockerfile: multi-stage node:20-alpine build, non-root
  user, dumb-init, /health HEALTHCHECK on :8080.
- Dockerfile (root, portal): multi-stage vite build → nginx:1.27-alpine,
  VITE_ORCHESTRATOR_URL baked at build time.
- nginx.conf: SPA fallback + long-cache /assets, sourcemaps denied.
- docker-compose.yml: full sandbox stack (postgres 15 + redis 7 +
  orchestrator + portal), all secrets parameterised via env_file.
- .env.sandbox.example: template with EXT-* blocker env vars documented
  and CHAIN_138_RPC_URL defaulting to the resolved public endpoint.
- .dockerignore: excludes node_modules, artifacts, cache, terraform, k8s.
- orchestrator/src/config/env.ts: emptyToUndefined() preprocess so zod
  optional regex fields validate empty-string identically to unset
  (fixes docker-compose NOTARY_REGISTRY_ADDRESS= sandbox booting).

Headless smoke test on this box:
- docker compose --env-file .env.sandbox up -d → all 4 containers
  reported Healthy.
- curl /ready → {"ready":true}
- curl portal / → HTTP 200 with correct <title>.
- orchestrator boot log prints all 7 EXT-* IDs (6 active, 1 resolved).
- /health returns 503 on this particular builder because memory is
  'critical' — DB + Redis both 'up'; this is environment-specific and
  not caused by PR Z.

Unit: 13 suites / 167 tests still pass after env.ts preprocess change.

+ * Machine-form obligation layer (gap-analysis v2 §4.1 partial).

+ * abort conditions, unwind conditions, authorized-participant matrix,
+ * and a reference to governing documents.
+ *
+ * Until now a Plan only stored a `templateHash` — a hash reference

+ *   - Strongly typed shape for the six architectural sub-objects
+ *     (consideration, validIssuance, validPayment, commit, abort,
+ *      unwind, authorizedParticipants, governingDocuments).
+ *   - Canonicalisation + SHA-256 hash (deterministic, replayable).
+ *   - Executable assertions built on the PR P Rules Engine DSL so
+ *     commit/abort/unwind conditions can be checked automatically
+ *     against a live context.
+ *
+ * Binds to the existing `InstrumentTerms.templateHash` field: an
+ * ObligationTerms instance records the governing-document hash as
+ * one of its `governingDocuments[]` entries, closing the loop from
+ * "which document governs this plan" to "what does that document
