This update enables users to select key tax document types – ‘80’ and ‘83’ – when creating invoices with the ‘Online Invoice’ AFIP POS System setting enabled. Previously, these document types were unavailable in this scenario. This change ensures compliance with Argentinian tax regulations and improves invoice processing for users operating within the AFIP system.

This pull request replaces https://github.com/odoo/odoo/pull/156598

Description of the issue/feature this PR addresses: It is necessary to be able to select document types "80 INFORME DIARIO DE CIERRE (ZETA) - CONTROLADORES FISCALES" and "83 TIQUE" in an invoice if the journal of the invoice has "Online Invoice" set on field "AFIP POS System".

Current behavior before PR:
User is not able to select document types "80 INFORME DIARIO DE CIERRE (ZETA) - CONTROLADORES FISCALES" and "83 TIQUE" in an invoice if the journal of the invoice has "Online Invoice" set on the field "AFIP POS System".

This update streamlines the setup of Odoo's email functionality by migrating existing configuration settings to a new system. This allows users to initially configure basic settings through the base module, then easily install the full mail module and its associated features, like website and server domain setup. It addresses a change in how email configuration is handled within Odoo, ensuring compatibility and a smoother installation process.

When adding alias domain in v17 support of configuration parameter was dropped. We moved from singleton configuration to multi domains using real models.

 This means most of mail support lies in mail while part of it was in base
beforehand. In some cases we want to let people do some basic configuration using base module then install mail which could migrate this ICP based configuration into new models. This is notably the case with odoo.sh where mail is not always automatically installed.

With this change existing ICP are now used to bootstrap alias domain table at mail module initialization.
