Add topics for bridge to forward

I have some additional topics I’d like the mosquito bridge to forward (unrelated to LoRaWAN and coming from WiFi connected sensors). How do I specify this in the configuration file(s)?

Specifying it in the configuration files would not be enough, as you still need to read the sensor data and publish this over MQTT. But why don’t you let your sensors directly publish their payloads over MQTT. I don’t see why you would need the LoRa Gateway Bridge for this.
