* Refactor migration error handling to use MinimumVersionError for schema version checks
- Updated migration logic to return MinimumVersionError instead of MigrationError for outdated schema versions.
- Enhanced MinimumVersionError message for clarity on migration constraints.
- Added tests for version error handling in the dashboard API to ensure proper error throwing for specific conversion errors.
* Fix tests and remove folder dependencies
