fix: remove dev-only IdeHelper provider registration causing 500 in prod

AppServiceProvider registered Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider
unconditionally. That package lives in composer.json require-dev and is never
installed by `composer install --no-dev` (used in docker/Dockerfile), so the
class doesn't exist in production, causing a fatal error on every request.
