Stock Lot Production Date

This module extends the existing lot/serial number screen in Odoo with one extra piece of information: the production date.

• On the lot/serial number form (the stock.lot record), a new "Production date" field appears right after the internal reference field. Users can fill it in manually with the date and time when the goods carrying that lot or serial number were produced.
• The field is a date and time value, and its on-screen help text explains that it is the date when the goods with this lot/serial number have been produced.
• No automatic calculation, validation, default value, email or scheduled action is added by the code; the date is simply stored on the lot record.
• The module only touches the lot/serial number area of Inventory (stock.lot); it does not change stock moves, deliveries, receipts or any other document.

In short, it is a small data-capture improvement: wherever you open a lot or serial number, you can now note its production date alongside the usual reference, and that value is saved with the lot.
