Add custom 404 and 500 error pages via ExceptionListener

Browse Source 
- Create ExceptionListener that renders custom error templates in prod
- Skip in dev environment to keep Symfony debug pages
- 404: neo-brutalist page with large "404" text and return link
- 500: generic server error page with status code display
- Add 4 unit tests (dev skip, 404 render, 500 render, other HTTP codes)
- Register kernel.environment parameter for ExceptionListener
