fix(quality): wire registryProp to App render so no-unused-vars passes (#269)

`registryProp` was declared but never passed to `App` in the render
function, causing the single ESLint `no-unused-vars` failure on the
quality CI job. Adds `registry: registryProp` to the render props so
the v2 component registry (registry.js) is actually forwarded to
CnAppRoot — matching the pattern used by procest/mydash.

Fixes ConductionNL/hydra#307
