Fix dummy app configuration for test environment

Set server_bundle_output_path to nil and enforce_secure_server_bundles to false
in the dummy app's React on Rails configuration. This ensures the dummy app
uses the standard webpack output location (public/webpack/test) where bundles
are actually built during tests, resolving the CI failures.
