fix(wifi): preserve AP_STA mode after WiFi.begin() kills the AP

Browse Source 
WiFi.begin() internally resets mode to STA, immediately destroying the
fallback AP that was just created. Fix: restore WIFI_AP_STA mode after
begin() when in AP mode, so TJ56654-Setup stays visible.

This was why the fallback AP was never visible despite being 'created'.
