Pull Request Description

This pull request addresses a critical bug identified in the post-upgrade process of the firewall upgrade script. Previously, the generation of post-upgrade snapshots and diff reports was skipped if a settings.yaml file was not present in the working directory. This pull request ensures that these crucial steps are executed regardless of the settings.yaml presence, thus guaranteeing the availability of post-upgrade snapshots and reports for every upgrade.
