feat(warehouse): P1 dashboard analytics — dwell/aging, cycle-time + on-time, live deltas

Adds the operational-performance layer to the warehouse cockpit:

- Dwell time & aging: dwellStats() (avg + 0-3/4-7/8-14/15+ buckets over
  in-warehouse items) → DwellAgingCard histogram.
- Cycle time & on-time: cycleStats() (arrived→ready→loaded→dispatched stage
  averages + dock-to-dispatch) and onTimeDispatchStats() (share of items that
  left before their storage free-days expired, resolved via the fee engine's
  own rule matching) → CycleTimeCard.
- Live tiles: opsStats() now returns receivedYesterday; KpiStrip renders an
  optional ▲/▼ delta, and the ops strip shows received-today vs yesterday.

New endpoints: GET /warehouse-inventory/{dwell-stats,cycle-stats} and
/warehouse-fees/on-time-dispatch (all guarded). New "Performance" section on
WarehouseDashboardPage. On-time reads N/A when there is no sample / no active
storage rule.
