feat(pos): reportes funcionales — ventas, inventario, ABC, cortes de caja

Replace static demo data with live API calls across all four report tabs:
- Ventas: sales by period/employee/payment method with date filters
- Inventario: valuation, ABC classification, low stock, no movement
- Clientes: accounts receivable aging report
- Financieros: income statement, balance sheet, trial balance, register history

All tabs use lazy loading (fetch on first visit) and JWT auth.
