feat: show free and total under each disk ring

Replaces the percentage, which the ring already draws as an angle. A number
repeating it costs a row in a column about 75px wide.

Free carries the threshold colour because it is the measured quantity; the
total is fixed and stays in the plain value colour, so each column has one
coloured number.

The cache card adopts card.truncate in the same pass: it was slicing names by
byte, which halves a multi-byte character.
