Stock product lot firmware version

This module extends the existing Lots/Serial Numbers feature in Odoo. It does not create a new screen; instead it adds one extra field, called Firmware Version, to the lot or serial number record.

Where it appears: - On the form used to view and edit a lot or serial number (the stock.production.lot form), the new Firmware Version field is placed right after the existing Reference field.

What users can do: - Open any lot or serial number and type or read the firmware version stored for that specific item. - Use the field to keep track of which firmware release is installed on each serialized electronic unit.

Business rules and automatic behaviour: - The code only defines a simple text field. There are no automatic checks, no computed values, no default values, no restrictions, no emails and no scheduled jobs.

Areas touched: - Inventory / Stock, specifically the lot and serial number records (stock.production.lot). - No other models, menus or reports are modified.
