10/17/25 - Adding some logging when the provisioner starts

10/18/25 - WiFi.begin() will put the WiFi in WIFI_STA mode automatically if it comes from WIFI_OFF. However, if the device is coming from WIFI_AP mode, WiFi.begin() will apparently put it in WIFI_AP_STA mode, and leave the DEVICE_PROVISIONING SSID active. So, best to explicitly call WiFi.mode(WIFI_STA) before WiFi.begin() in src/main.cpp.
