## Summary
- complete Spec 136 canonical admin tenant rollout across admin-visible and shared Filament surfaces
- add the shared panel-aware tenant resolver helper, persisted filter-state synchronization, and admin navigation segregation for tenant-sensitive resources
- expand regression, guard, and parity coverage for admin-path tenant resolution, stale filters, workspace-wide tenant-default surfaces, and panel split behavior
## Validation
- `vendor/bin/sail artisan test --compact tests/Feature/Guards/AdminTenantResolverGuardTest.php`
- `vendor/bin/sail artisan test --compact tests/Feature/Filament/TableStatePersistenceTest.php`
- `vendor/bin/sail artisan test --compact --filter='CanonicalAdminTenantFilterState|PolicyResource|BackupSchedule|BackupSet|FindingResource|BaselineCompareLanding|RestoreRunResource|InventoryItemResource|PolicyVersionResource|ProviderConnectionResource|TenantDiagnostics|InventoryCoverage|InventoryKpiHeader|AuditLog|EntraGroup'`
- `vendor/bin/sail bin pint --dirty --format agent`
## Notes
- Livewire v4.0+ compliance is preserved with Filament v5.
- Provider registration remains unchanged in `bootstrap/providers.php`.
- `PolicyResource` and `PolicyVersionResource` have admin global search disabled explicitly; `EntraGroupResource` keeps admin-aware scoped search with a View page.
- Destructive and governance-sensitive actions retain existing confirmation and authorization behavior while using canonical tenant parity.
- No new assets were introduced, so deployment asset strategy is unchanged and does not add new `filament:assets` work.
