🛠️ Ability to add warranty field period to a Product

When creating products, it would be helpful to have the ability to designate whether the product has a warranty period that should be recorded on the invoice.

Aligning with consumer law best practice, warranty expiry dates for items sold should appear on the invoice. As this is simply to meet requirements for manufacturer end-of-support dates, extended warranty coverage, and for clients who need these records for depreciation and asset registers, we do not need automated warranty calculations, reminders, or contract management functionality.

The product would have an additional field: ‘Warranty Period’.

Generally, this is a term in months or years from the invoice date, so this field could allow selecting a number plus whether it is measured in months or years (e.g., 3 months, 2 years), calculated from the invoice date into the line item.

When a product with a Warranty Period is added to an unapproved invoice, it would automatically populate the field with the details from the Product. Once in the invoice, it should be possible to overwrite the default or delete it so that it does not show on the invoice.

This would appear on the invoice below the product details and the serial number if that feature is added.
