Stock Picking Assign Serial Final

This module makes it easier to register a whole range of serial numbers at once when receiving products.

• On the serial number assignment wizard (the screen where you type the first serial number), a new 'Final SN' field appears right after the starting serial number.
• On the detailed operations screen of a stock move, the same 'Final SN' field is shown next to the starting serial number, but only when serial number assignment is available for that move.
• Odoo reads the numbers inside the starting and final serial numbers and automatically computes how many serial numbers will be created (the difference plus one). This count is stored and can be adjusted by the user.
• If either the starting or the final serial number is missing, the count is set back to zero.
• When the detailed operations screen is opened, any previously entered final serial number is cleared so the user starts fresh.

It touches the stock move model (stock.move) and the serial number assignment wizard (stock.assign.serial), and it depends on the standard Inventory (stock) module. No new menus or reports are added; the change is visible directly in the existing serial number assignment and detailed operations screens.
