#12154 e36c0c9 Thanks @petebacondarwin! - Use X-Forwarded-Host header for extension authority when behind a proxy
When Quick Edit is accessed through a proxy, the X-Forwarded-Host header is now used to determine the authority for loading builtin extensions. This ensures extensions load correctly when the Worker is behind a reverse proxy. The header value is only used if it matches *.devprod.cloudflare.dev for security.
