[FIX] account_peppol: fix saving of the verification code

When the verification code is saved,
it triggers the full save and and users get errors about other required fields, e.g. website language missing.
This commit removes save on every focusout, as the save is triggered when clicking confirm.

closes odoo/odoo#147037
