feat: implement version-based migrations for global settings

- Added versioning to global settings, enabling automatic migrations for breaking changes.
- Updated default global settings to reflect the new versioning schema.
- Implemented logic to disable sandbox mode for existing users during migration from version 1 to 2.
- Enhanced error handling for saving migrated settings, ensuring data integrity during updates.
