This update ensures Odoo's cron jobs maintain transactional consistency by adding a rollback function. Previously, using these functions outside of cron jobs could disrupt data integrity. This change enhances the reliability of automated processes within Odoo.

For the symmetry of the API, adding `_rollback_progress` to `_commit_progress`. This also allows us to check which commits or rollbacks are used in models, because using them in models outside of cron jobs breaks the transactional behaviour of Odoo.
