Add BLE diagnostics: controller status, MAC, advertising result

Browse Source 
Remove getMinInterval/getMaxInterval (not available in v1.4.0).
Add esp_bt_controller_get_status() before/after init.
Add esp_bt_dev_get_address() for MAC address.
Print adv->start() return value.
Add explicit advertising interval settings (100-200ms).
