Architect-review remediation: enforce conventions, prod-safe tooling, one form idiom, resilience seams

Acts on the showcase review. Four workstreams; all tests green
(npm run lint, 70 FE tests, ng build, 33 backend tests).

Enforcement + CI:
- eslint.config.mjs bans `any` and enforces layer/context boundaries
  (domain ≠ Angular; herregistratie → registratie → shared, auth → shared);
  `npm run lint` added; ajv 6 scoped to ESLint via nested override.
- .github/workflows/ci.yml: FE lint+check:tokens+test+build, backend dotnet test,
  and an API-client drift check.

One form idiom (the headline finding):
- change-request-form converged onto the wizard pattern — change-request.machine.ts
  (Model/Msg/reduce + value objects) + submit-change-request.ts (Result) + a real
  POST /api/v1/change-requests (server re-validates). Spec + story added; the detail
  page no longer holds an ad-hoc success signal.

Resilience/observability seam:
- api-client.provider.ts: request timeout, X-Correlation-Id, Idempotency-Key for
  writes; comments naming the retry/auth seams.
- Backend logs correlation id + a no-PII submit-audit line; /api/v1 prefix +
  backward-compat note; client regenerated.

Quick wins:
- Dev tooling excluded from prod: scenario.interceptor wired only under isDevMode()
  (?scenario= inert in prod); debug panel @if(isDev) (tree-shaken out).
- src/environments + apiBaseUrl into provideApiClient (angular.json fileReplacements).
- Backend /health + /health/ready.
- Debug view PII-minimised (redactProfile: name/address/DOB redacted, BIG masked).
- IntakePolicyAdapter (removes inline resource in the intake wizard).
- README de-staled; CLAUDE.md gains EN/NL + forms-one-idiom + lint/CI notes.
- Stories: text-input, link, data-row, site-header, site-footer, change-request-form.
