[FEAT]: Option to switch between LoRa and MQTT when sending messages.

[th3cavalry]

Feature Description

Feature or improvement you want.

When connected to MQTT there should be a way to bypass MQTT and send a message over LoRa.

Why should this be added?
People who travel but want to temporarily talk locally without having to totally disable MQTT on their devices.

Also people who are testing setups and deployments.

Screenshots / Drawings / Technical details
Maybe a little toggle switch per channel or if you long press send it brings up an option to send over radio.
