Issue
The header on docs pages (e.g. https://exe.dev/docs/what-is-exe) displays "Sign in" regardless of whether the user is authenticated or not.
Expected Behavior
The header should display the same authenticated user information as shown on https://exe.dev/user when the user is signed in.
Current Behavior
The header always shows "Sign in" even for authenticated users on documentation pages.
