ESP32-S2: Log all Wi-Fi events & remove unneeded call

[anecdata]

init.c:

Add logging to the event handler default event to capture any other wi-fi events that occur, to see what else happens in the field that we may want to handle better.

Radio.c:

This call in start_station():

esp_wifi_set_config(WIFI_MODE_STA, &self->sta_config);

has the wrong parameter [type] (should be ESP_IF_WIFI_STA == 0; WIFI_MODE_STA == 1 and sets the config for AP interface type ), and is also not needed here since it's called in connect() anyway (and is not needed for scanning or ping).

Alternatively, we could correct the call in start_station(), and remove it from connect() (connect() calls start_station())

All depends on the design intent... how granular we want these functions to be as features like AP, AP+STA, etc. get added. It might be nice to keep clean code demarcation between concepts of netif [de]init, wifi [de]init, wi-fi mode, wifi start/stop, and station [dis]connect.

Not early log please.

Looks good! Thank you!

Partially addresses the logging aspect of #3837.
