feat: QSO rate meter — per-operator AND team totals

GetQSORate now returns both the active operator's rate (their own performance)
and the whole station's rate (all operators combined). RecentRateBreakdown
computes both in one scan of the recent rows (per-operator + all-operators),
replacing RecentRate.
