Configures forwarded headers for the application

Ensures the application correctly handles forwarded headers
by explicitly setting the `ForwardedHeaders` option to `ForwardedHeaders.All`.

This allows the application to properly determine the client's
IP address and other request information when behind a proxy
or load balancer.
