AckdbDashboardKpiSpec

One number. `count` is the segment's row count and takes NO field; every other agg requires a numeric catalog FIELD KEY (numeric traits/attributes, `sc__` score columns, `evc__` per-event-type counts, `emf__` promoted event fields). Contact-aggregate (#214) and event-aggregate (#413) columns are inline column specs, not field keys, so they cannot be named here.
