fix(astal-menu): single module border; unblock rfkill so Bluetooth powers on

- Borders: with the app stylesheet now above the theme, the CSS `.quad-card`
  border rendered a second ring concentric with the Cairo bordered() ring. Drop the
  CSS border/background/radius from the card boxes so only the Cairo card shows.
- Bluetooth: the power/scan/connect controls were correctly wired to AstalBluetooth,
  but the adapter was rfkill soft-blocked, making set_powered a silent no-op. The
  power toggle now runs `rfkill unblock bluetooth` before powering on.
