Settingsscreen.h — added isInWifiNetworkSelect() (returns true while EDIT_WIFI + WIFI_PHASE_SELECT), sitting next to isInWifiPasswordEntry().

main.cpp — added a dispatch block in the Settings handler: when the network picker is showing and key=='\b' with shift consumed, it calls ui_task.injectKey('q'), which runs the existing 'q' exit path synchronously (tear-down of EDIT_WIFI, onboarding handling, wifiReconnectSaved()) and refreshes. So Shift+Del and Q now both exit the picker, with no duplicated exit logic.
