feat(auth): explain the plain-HTTP secure-cookie gotcha on login

When the server issues a Secure session cookie but the request arrived over
plain HTTP (the common LAN install over http://ip:3000), the browser drops
the cookie and the next request dead-ends on a bare "Access token required" —
the top source of avoidable install issues. The login response now flags this
exact case and the login page shows a localized box explaining the fix (use
HTTPS, or set COOKIE_SECURE=false) with a link to the Troubleshooting guide.
It only triggers in the real failure case, never for correct HTTPS setups.
