Show the confidence, and say which curve it came from

FR-CULL-9 was read as "no fit, no number", so every library without 200
confirmed positive pairs showed "Confidence unavailable" on every
suggestion — which is every library, until enough confirmations exist to
fit one. The confirmations are made on this screen, ranked by the number
it was withholding, so the degraded state was also the permanent one.

There has always been a curve: Calibration::default is the reference
implementation's fitted MBF sigmoid, which is what clustering already
operates at. It is a published operating point, not an invention, and
what the requirement forbids is presenting it *as though it were
measured on this library*. So the percentage is shown, and the screen
says once, above the grid, where the curve came from.
