## Summary
- retire the remaining tenant-scoped provider-connection legacy routes and update canonical verification and link behavior
- complete the provider target-scope fallback cleanup so neutral shared scope data falls back to the managed environment when the raw connection tenant identifier is blank
- stop mirroring workspace roles into managed-environment scope persistence and cut the targeted admin-panel test helpers over to the post-cutover context path
- add and update the Spec 287 artifact package and targeted regression coverage for route retirement, provider-core neutralization, workspace-first RBAC, and helper cutover
## Validation
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/ProviderConnections/LegacyRedirectTest.php tests/Feature/ProviderConnections/TenantlessListRouteTest.php tests/Feature/ProviderConnections/TenantlessListScopingTest.php tests/Feature/Auth/WorkspaceFirstManagedEnvironmentAccessTest.php tests/Feature/Rbac/ProviderConnectionWorkspaceFirstPolicyTest.php tests/Feature/Reviews/CustomerReviewWorkspaceLaunchLinksTest.php tests/Feature/Rbac/TriageReviewStateAuthorizationTest.php`
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Browser/Spec281ProviderConnectionScopeSmokeTest.php tests/Browser/Spec285WorkspaceRbacEnvironmentAccessSmokeTest.php`
- `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`
## Notes
- Filament remains on Livewire v4 and provider registration stays unchanged in `apps/platform/bootstrap/providers.php`.
- No new asset registration or deployment-step changes are included in this slice.
