feat(measurements): value-range filter on the management list

Add an optional numeric value-range filter to the measurement list:
readings whose `value` falls within `[valueMin, valueMax]`, either bound
omittable for an open-ended range. Server-authoritative — both bounds are
parsed on `listMeasurementsSchema` (coerced from the query string), an
inverted `valueMin > valueMax` returns 422, and the bounds thread into the
Prisma `where` as a `value: { gte, lte }` range on the raw per-sample list.

The filter rides a new `FilterBarNumberRange` pill that mirrors the existing
date-range control, hidden for the day-grouped and sleep-night types where
the painted value is a synthesised total rather than a stored reading.
