v1.13.4: Standardize all route responses to use response helpers

Convert ~160 raw res.json()/res.status().json() calls across 32+ files
to use centralized helpers from src/utils/responses.js (ok, errorResponse,
successMessage, notFound, validationError, forbidden, unauthorized, conflict).

No behavior changes — response shapes are identical. Future schema changes
(e.g., requestId envelope) only need to update one module.

Fix error vs errorResponse signature mismatch in routes/health.js CA cert
endpoint where error(res, message, statusCode) was being called with
errorResponse(res, statusCode, message, extras) argument order.

Files changed: middleware.js, csrf-protection.js, error-handler.js,
license-manager.js, src/app.js, and 27 route files.

Test suite: 755 pass / 4 pre-existing failures (services credential tests).

 ## [Unreleased]
 
+## [1.13.4] - 2026-06-12
+
+### Changed
+- Standardized all route handler responses to use helpers from `src/utils/responses.js`
+  (`ok`, `errorResponse`, `successMessage`, `notFound`, `validationError`, `forbidden`,
+  `unauthorized`, `conflict`). ~160 raw `res.json()` calls converted across 32+ files.
+  No behavior changes — response shapes are identical. This ensures future schema
+  changes (e.g., adding a `requestId` envelope) only need to update one module.
+- Fixed `error` vs `errorResponse` signature mismatch in `routes/health.js` CA cert
+  endpoint. The `error` helper takes `(res, message, statusCode)` while `errorResponse`
+  takes `(res, statusCode, message, extras)` — the wrong alias was being used for
+  calls that needed the 4-argument form.
+- Updated `middleware.js`, `csrf-protection.js`, `error-handler.js`, and
+  `license-manager.js` to use response helpers for rejection/error responses
+  instead of inline `res.status().json()`.
+
+### Note
+- 4 pre-existing test failures in `services.routes.test.js` (credential storage)
+  remain from before this release. They are unrelated to the standardization pass.
