* feat(provisioning): add generic version handling for dashboard export
- Update export job to handle any dashboard version generically (v0, v1, v2, v3, etc.)
- Dynamically construct GroupVersionResource for any stored version
- Cache version-specific clients for efficiency
- Add comprehensive table-driven unit tests for multiple versions
- Add integration test to verify version handling end-to-end
- Remove unnecessary version shim from clean operation (deletion works by name)
* test: add unit test for v2 dashboard version (no suffix)
