- Added missing i18n keys for import results in both root and common locales.
- Fixed TypeScript type errors and implicit 'any' types in TenantListPage.
- Added 'destructive' variant to common Badge component.
- Updated Playwright tests with refined locators and enhanced API mocks to match the new reporting structure.
- Restored quick summary message in Tenant Registry for backward compatibility.
