Make the referee dashboard's season stats one compact row, not two

KPIs and the chart now share a single flex row (chart card wider, flex-[3])
instead of a full KPI row followed by a tall standalone chart card -- the
per-referee fee breakdown moves into the chart's own tooltip instead of a
separate list underneath, so this stays compact and the actual
games-needing-a-referee list isn't pushed below the fold.
