Product Analytic

This module adds a new 'Analytic' section to product and product category forms where you can list analytic distribution models.

• On a product form, a new Analytic group appears after the properties group, with a list of analytic distribution models linked to that product.
• On a product category form, the same kind of list appears after the accounting properties group, linked to the category.
• Each line in the list can define a sequence (drag handle to reorder), an account prefix, a partner, a partner category, the product or product category, a company, and the analytic distribution itself.
• The product field is read-only on the product form, and the product category field is read-only on the category form, so the link stays consistent.
• The company field is only shown to users who can work with multiple companies.
• The analytic distribution widget is used to enter the distribution, with applicability optional and saving disabled in the list.

The module extends product.product and product.category and relies on account.analytic.distribution.model from the Accounting app. It does not add menus, reports, or scheduled actions; it only adds these configuration lists to existing product and category screens.
