[FEATURE] Thruster assignment

[benjaminwp18]

Is your feature request related to a problem? Please describe

We have a thruster assignment widget that's theoretically supposed to test whether our thrusters work and allow us to assign which pins control which thrusters. It doesn't.

Describe the solution you'd like

Get the widget working. You might want to take a look at this branch from 2024, but keep in mind that this branch didn't end up working. It's OK if the robot disarms between thruster tests, as long as the pin assignment and testing works.

The code to do this is in place, but for some unknown reason the client node can't connect to the mavros/param/set service
