Metric settings (display text, direction & how Month/Year combine weekly values)
Icon and phrase control how a metric reads on the overview cards (e.g.
💰 + "flagged for recovery" → "💰 $4,989 flagged for recovery"); leave
blank to fall back to an auto-generated phrase. Unit controls number
formatting ($/€ prefix, % suffix). By default a metric going up is shown
as good (green), and Month/Year views add up the weekly values (right
for counts and € totals) — mark a metric here if going down is actually
good, or if it's a rate/percentage that should be averaged instead of
summed. All changes apply to the overview cards immediately.
