This update organizes UBL test files for better compatibility with future move formats and improved schema validation. The change improves the structure of the test files, streamlining development and testing efforts related to UBL invoice processing. This supports ongoing improvements to our invoicing capabilities.

This commit rearranges the UBL test files' subfolder to be one level higher, from `export/bis3/be` to `export/bis3/invoice/be`, in preparation for supporting different move formats and for better ignore schema support.

This update enhances the reliability of IoT Box connections by directly using IP addresses instead of domain names. This change, enabled when 'LNA' is active, prevents potential issues caused by DNS resolution delays. It ensures smoother data transmission from IoT devices to the Odoo system.

In order to avoid DNS resolution issues, we now parse the domain to get the IP of the IoT Box if LNA is enabled.

This update adds a comprehensive list of VAT exemption reason codes (VATEX) to the Odoo system. Previously, the available codes were limited, which could cause issues with accurate VAT reporting. This change ensures compliance with EN16931 standards and improves the system's ability to handle various VAT exemption scenarios.

The list is there but not exhaustive.

Make the exhaustive list of VAT exemption reason codes (VATEX) available.
