Stock Package Type Volume

This module extends the package type configuration in Odoo's Inventory/Stock area. On the package type form, next to the existing size fields, a new read-only Volume value is displayed together with the volume unit of measure used by the company.

The volume is calculated automatically from the package's length, width and height. The dimensions are first converted to meters using the company's configured length unit, then multiplied together to obtain a volume in cubic meters, and finally converted into the company's configured volume unit of measure. If any of the three dimensions is missing, the volume is shown as zero.

The volume unit of measure is taken from the same configuration used for products, so it stays consistent with the rest of Odoo. The value is computed on the fly and is not stored, meaning it refreshes whenever the dimensions or the unit of measure change.

This affects the stock.package.type model and its form view. No new menus, buttons, reports or scheduled actions are added; the change is limited to showing the computed volume on the existing package type screen.
