improvement(usage): drop the segmented allowance meter from the usage summary (#7202)

The pills answered a question the line above them had already answered. "511,488
credits of 2,000,000" is the proportion, stated exactly; a 24-segment bar restates
it approximately, and directly under a chart of the same data in the same colour it
reads as a third series rather than as a summary.

The seat meter keeps `SegmentedMeter`, where it belongs: seats are countable, so a
pill per seat is legible in a way a pill per ~83,000 credits is not. The overage
signal the meter also carried is unaffected — the "Over limit" badge beside the
figure already states it, and states it in words.
