M1 step 2: Wi-Fi Service, Saved Networks, NTP, Settings page

- lib/wifi (host-tested): SavedNetworks (up to 8, validated, hidden flag, persisted) and WifiController (joins the strongest Saved Network, tries hidden ones in turn, backoff 10/30/60 s, connect timeout, Monitoring override, radio off without Saved Networks) - WifiService carries out the controller's actions, sets the EU country code, and syncs the Clock over SNTP without touching the TZ - Wi-Fi On/Off setting; Settings > Wi-Fi page: status, add from a scan or a hidden network, forget - Status Bar: W + signal bars, W? while searching, MON while monitoring - Serial: wifi add / wifi status (replaces the step 1 heap probe) Verified on the device: joins the test network ~5 s after boot, clock set over NTP, ~129 KB free heap while connected.
