Subject: [PATCH] [TASK-2026-01-20-001] feat: Add API clients for products,
 inventory, warehouses and billing

EPIC-003: Clientes API frontend web
- products.api.ts: CRUD operations for product management
- inventory.api.ts: Stock levels, movements, adjustments, transfers
- warehouses.api.ts: Warehouse and location management
- billing.api.ts: Invoices, payments, credit notes, debit notes
- Updated index.ts with new exports

Coverage increased from 5.7% to ~25% of backend endpoints
