Guest Wi-Fi dashboard card (network + rotating password + join QR)

New home card 'unifi.guest_wifi': shows the guest SSID, the current
rotated password (unifi.password_rotation.last_password), and a WPA
join QR built from the WIFI: string. Polls app/unifi/guest-card/data
(auth) every 60s so it updates the moment the rotation engine changes
the password — the QR regenerates client-side to match. Self-hides
until enabled with an SSID and a rotated password; grant-gated via
Admin -> Settings -> Dashboard Cards. New settings (WiFi rotation
section): enable + network name + card title.
