AI-generated from the code · Odoo 14.0

Adds German SteuerNummer (tax number) validation to partner records, so Odoo can check whether a German tax number entered on a contact looks valid.

This module extends the standard VAT validation of Odoo to cover the German SteuerNummer (tax number) used on contacts.

When a German tax number is checked on a partner, Odoo first tries the external vatnumber library. If that library is not installed or does not confirm the number, the module falls back to a simple rule: it removes every non-digit character and accepts the number only if it contains 10 or 11 digits.

It works on the res.partner model, the same place where customer and supplier tax IDs are stored.
It adds the German-specific check check_vat_de, which is used by the standard VAT validation flow from base_vat.
No new menus, screens, buttons or reports are added; the behaviour appears wherever a partner's tax number is validated in Odoo.
No automatic emails, scheduled jobs or extra fields are introduced.

In short, it helps German companies avoid saving obviously wrong tax numbers on their contacts, while keeping the normal Odoo VAT validation behaviour.
