## Summary
- add the RBAC role definition diff UX upgrade as the first concrete consumer of the shared diff presentation foundation
- refine managed tenant onboarding draft routing, CTA labeling, and cancellation redirect behavior
- tighten related Filament and diff rendering regression coverage
## Testing
- updated focused Pest coverage for onboarding draft routing and lifecycle behavior
- updated focused Pest coverage for shared diff partials and RBAC finding rendering
## Notes
- Livewire v4.0+ compliance is preserved within the existing Filament v5 surfaces
- provider registration remains unchanged in bootstrap/providers.php
- no new Filament assets were added; existing deployment practice still relies on php artisan filament:assets when assets change
