IMEI/Serial Number integration

The requirement is to have an IMEI/Serial Number function similar to the Lot number but with distinct differences.

• The IMEI/Serial number feature needs to be enabled in settings (similar to how the lot number is enabled in settings-purchase).

• Once activated, it should display in the Opening Stock, Purchase, Sell, and POS sections. In Sell/POS, the functionality to search by Serial/IMEI is necessary, akin to the lot number.

• The invoice should display the Serial/IMEI number, just as it shows the lot number.

• Reports should indicate which serial numbers have been sold and which remain in stock. In the item report section, where the lot number report is visible, a similar report for serial numbers is required.

• It is crucial that the Serial/IMEI number can be input using a comma, a pipe ("|"), or by pressing enter, unlike the lot number which does not have this feature.

• Each SKU may have multiple stocks, and each stock must have a unique Serial/IMEI number.
