This update adds support for using and testing Odoo's paper-muncher report rendering tool, including timeout handling for web-based report processing. It helps improve reliability when generating or validating printable documents.

This update allows tax return period calculations to be adjusted when needed, instead of always relying on the current configured period. This helps migration processes accurately recreate older returns whose dates may not match today's settings.

The method _get_period_boundaries not allow to override the targetted period and start_date.

This is used for the migration script to recreate old returns that not always has the same period as the one configured.
