fix: logout route accepts GET to prevent 404 on page refresh

POST /logout redirects to / after logging out, but when the redirect
fails to complete (browser/network quirk) the user is stuck on /logout.
Refreshing sends GET, which had no route defined, causing a 404.

Changed Route::post to Route::match(['get', 'post']) so refreshing
after a stuck redirect gracefully completes the logout instead.
