* Default to folder sync only and block new instance sync repositories
- Change default allowed_targets to folder-only in backend configuration
- Modify validation to only enforce allowedTargets on CREATE operations
- Add deprecation warning for existing instance sync repositories
- Update frontend defaults and tests to reflect new behavior
Fixes#619
* Update warning message: change 'deprecated' to 'not fully supported'
* Fix health check: don't validate allowedTargets for existing repositories
Health checks for existing repositories should treat them as UPDATE operations,
not CREATE operations, so they don't fail validation for instance sync target.
* Fix tests and update i18n translations
- Update BootstrapStep tests to reflect folder-only default behavior
- Run i18n-extract to update translation file structure
* Fix integration tests
* Fix tests
* Fix provisioning test wizard
