The src/ module-flattening refactor regressed the DC-001 fix: the 3
service-credential routes in routes/services.js used '/:serviceId/credentials'
instead of '/services/:serviceId/credentials', causing 4 test failures
(services.routes.test.js → 404 instead of 200) — every other route in the
file uses the '/services' prefix.
Also fixed a latent ReferenceError in the same validation branches: they
called ctx.errorResponse() but ctx is never defined in this module's scope
(the factory destructures its deps). Replaced with the imported errorResponse
helper so invalid serviceIds now return a clean 400 instead of crashing 500.
Tests: 4 failed → 0 failed (750 pass). ESLint: no new warnings.
