Feature Request - Test Button

[Hiltronix]

Thank you for sharing your OctoPrint plugin with us.

I have a feature request. Would it be possible for you to add a Test Send button to the plugin's "Signal Notifier Configuration" screen?

When I was first setting it up, I had trouble setting the correct "path to signal-cli" string. And I had to do several test prints to see when it worked. And now the plugin has stopped working for me, and if I had a Test Send button to quickly send a test message, it would be much easier to diagnose the problem.

Thank you for considering my feature request.

This would be super useful. I'm able to send messages from the CLI, but Signal-Notifier never sends any messages so I suspect some sort of a configuration issue with the plugin itself. A test mechanism would be super helpful.
