The tab doesn't take up much space, just drill a small intent in the panel. The drill should be a little wider than the tab and be careful not to drill too deep: the hole should be blind, i.e. not go all the way through the panel.

There is no reason why it should not go through the panel unless you use tiny knob.

And after some time, nut becomes a bit loose and problems start to happen.

And abuse pot/PCB even before device was made.

Would a few drops of cyanoacrylate onto potentiometer threads under nut prevent it from becoming loose?

Yes, but then undoing it will be virtually impossible.

Pliers should take it off quickly after initial turn breaks adhesive.
