Quattro hands wifi to NetworkManager, which starts wpa_supplicant through
D-Bus activation. Installs carrying a wpa_supplicant.service mask from the
iwd days break that activation: NetworkManager retries five times, gives
up, and every wifi device sits at "unavailable" with no network to
research the fix on. Remove the mask (including a runtime one) and restart
an active NetworkManager when a wifi device is stuck, so wifi comes back
without a reboot.
