This update enhances the tracking of errors received from Intervat during tax return processing. Instead of just displaying notifications, error messages are now logged within the tax return chatter, providing better visibility and troubleshooting capabilities. This improves our ability to quickly identify and resolve issues related to Intervat tax returns.

When we receive an error from Intervat, we just display a notification. But
it's not optimal to track the errors of a tax return.

With this commit, we will also log the error messages in the tax return chatter.
