Warehouse Inventory Picking and Shipping

A comprehensive Warehouse Inventory Picking and Shipping system has been added to product management in the Ticket's Expenditures tab. You can now create, edit, and delete picking/shipping details for products, including:

• Select warehouse locations and bins from available inventory
• Manage serial numbers with barcode scanning support for serialized items
• Track picked and shipped quantities with validation
• Assign shipment methods, tracking numbers, and expected arrival dates
• View and refresh all picking/shipping details in a centralized modal

The interface includes a 4-step wizard for creating new entries and supports both serialized and non-serialized inventory items with full dark theme support.
