Spec 196: restore native Filament table contracts (#236)
## Summary
- replace the inventory dependency GET/apply flow with an embedded native Filament `TableComponent`
- convert tenant required permissions and evidence overview to native page-owned Filament tables with mount-only query seeding and preserved scope authority
- extend focused Pest, Livewire, RBAC, and guard coverage, and update the Spec 196 artifacts and release close-out notes
## Verification
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/InventoryItemDependenciesTest.php tests/Feature/Filament/InventoryItemDependencyEdgesTableTest.php tests/Feature/Rbac/TenantRequiredPermissionsTrustedStateTest.php tests/Feature/Filament/TenantRequiredPermissionsPageTest.php tests/Feature/Evidence/EvidenceOverviewPageTest.php tests/Feature/Filament/EvidenceOverviewDerivedStateMemoizationTest.php tests/Feature/Guards/FilamentTableStandardsGuardTest.php tests/Unit/TenantRequiredPermissionsFilteringTest.php tests/Unit/TenantRequiredPermissionsOverallStatusTest.php tests/Unit/TenantRequiredPermissionsFeatureImpactTest.php tests/Unit/TenantRequiredPermissionsFreshnessTest.php tests/Unit/TenantRequiredPermissionsCopyPayloadTest.php` (`45` tests, `177` assertions)
- `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`
- integrated-browser smoke on localhost for inventory detail dependencies, tenant required permissions, and evidence overview
