Account for forwarding headers when deriving base URL.

Prioritise standard Forwarded header, look for non-standard X-Forwarded-* if missing. Default to what can be derived from the URL if no headers provided. Middleware updates the host header that is interpreted by starlette when deriving Request.base_url.
