Remove simulation checks (#1507)

* Add cli rollback command

it's useful in app-hash mismatch situation.

* Update CHANGELOG.md

* (refactor): removed old sim tests logic

* (fix): removed tests from CI

* (fix): fix test.yml

* (fix): format and lint

* (fix): fix linter issue

* (fix): fix linter issues v2

* (fix): linter

* (fix): removed sim-test references

* Applied changes from code review
