1. Stock Count fix: dispatch StockCountCompleted event after completing
   a count so the ProcessCountAdjustments listener creates inventory
   movements. Made listener synchronous for immediate feedback.

2. Stock Adjustment: route now points to the existing wizard component
   instead of the plain form.

3. Purchase Orders: new CreatePurchaseOrderWizard with 4-step flow
   (supplier → warehouse/dates → items → review & confirm).
