Subject: [PATCH] fix(@angular/ssr): prioritize options over environment
 variables in AngularNodeAppEngine

Prioritize constructor options over environment variables when initializing the AngularNodeAppEngine. Previously, environment variables took priority and blindly overrode the constructor options if they were defined in the environment. Now, explicit constructor options act as the override, while the environment variables serve as a fallback.
