Yeah, that's what I pretty much expected to hear

It's a pretty simple mechanism. As I wrote: Imagine a long screw hooked to the backstay. Screw is threaded thru the center of a wheel. Bottom of the screw has a rectangular block on it that is captured such that the screw can't turn. There's not much that can go wrong with it.

I understand. And I suspect you're right
. An expensive lesson in why not to forget or put off even simple maintenance.
I'll first try the lubrication. If that doesn't resolve the problem, next I'll find a competent machinist. If re-tapping/-threading won't make it usable
and reliable again, maybe the machinist can fabricate new parts more cheaply than a whole new tensioner would cost. If not: Then we'll have to decide whether to bite the bullet and replace it, or just do w/o a backstay tensioner.
Thanks for your comments, Robert.
