Add new models UnitOfMeasure and ProductSalesUnit to enable selling products in different units (e.g., bunches, kg). Update Product model with base_unit field and methods for unit conversions and availability. Extend Sale, Reservation, and OrderItem models with sales_unit fields and snapshots. Modify SaleProcessor to handle quantity conversions. Include admin interfaces for managing units. Add corresponding database migrations.
