Product Sticker on Invoice Reports with Risk Insurance

This module connects product stickers (the small logos or labels printed on invoice reports) with credit policy companies used for risk insurance.

• On each product sticker, a new field lets you choose a Credit Policy Company. The sticker will then only be shown for invoices linked to that company.
• On the credit policy company form, a read-only list shows all stickers assigned to it, so you can see at a glance which logos are tied to that insurer.
• On invoices, the system automatically filters the stickers: a sticker is kept only if the invoice's credit policy state indicates that invoices are insured and the sticker belongs to the invoice's credit policy company. Otherwise the sticker is removed from the invoice report.

This means the insurance company logo appears on the printed invoice only when the sale is really covered by that insurer's policy, avoiding misleading logos on uninsured invoices.

The module touches account.move, credit.policy.company and product.sticker, and adds fields to the credit policy company and product sticker forms. It installs automatically when both risk insurance and invoice product sticker modules are present.
