feat: add cash in/out UI and hide drawer balance from cashier

- Cash In / Cash Out buttons in drawer dialog when open
- Amount + reason form, adjustment history with IN/OUT badges
- Drawer badge shows "Drawer Open" without balance (manager info only)
- API helpers for addAdjustment and getAdjustments
