Two cleanups in one pass for the v1.14.0 'works on any platform' theme: 1. Response helpers — merged src/utils/responses.js and the root-level response-helpers.js into a single module at src/utils/responses.js. The old module had a richer set (created, noContent, validationError, unauthorized, forbidden, notFound, conflict) and is now re-exported from the new location. Updated 15 routes to import from src/utils/responses and deleted the root response-helpers.js. 2. Error logger — error-handler.js now uses the unified src/utils/logging.js#logError (same one src/app.js uses), so all errors go to one log file with one rotation policy. Removed the dead asyncHandler export (the real one is in src/utils/async-handler.js and is used everywhere). Deleted the legacy error-logger.js. Both are invisible to users — same HTTP response shapes, same log file path, same error format. Internal-only refactor.
