Implementation Plan: Spec 332 - Restore Run Preview Productization (Wizard Safety Gates)

Summary

Productize the Restore Run wizard preview step so it remains decision-first and truthfully gated:

Block navigation to confirmation until checks + preview are current and execution is technically allowed.
Collapse “safety gates” detail by default; show concise guidance first.
Improve preview toast copy so it communicates real meaning (no scope, no changes, changes).

Wizard logic:
- apps/platform/app/Filament/Resources/RestoreRunResource.php
Copy:
- apps/platform/app/Support/RestoreSafety/RestoreSafetyCopy.php
Preview component:
- apps/platform/resources/views/filament/forms/components/restore-run-preview.blade.php
Tests:
- apps/platform/tests/Feature/Filament/RestoreRunPreviewProductizationTest.php
- apps/platform/tests/Browser/Spec332RestoreRunWizardPreviewSmokeTest.php

Wizard gate enforcement
- Add afterValidation gate on the Preview step.
- Evaluate existing restore safety state (wizardSafetyState) to check:
  - preview integrity is current
  - checks integrity is current
  - execution readiness is allowed
- Block navigation using Filament\Support\Exceptions\Halt and a clear Notification message.
Decision-first preview UI
- Keep safety details collapsed by default, with an explicit “View safety gates” affordance.
- Ensure primary preview content remains readable (avoid noisy type/platform copy in the main list).
Tests
- Feature test: confirmation guidance copy and preview readability.
- Browser smoke: run checks + generate preview, then assert gates are collapsed and execution is shown as unavailable.

Narrow first:

cd apps/platform && ./vendor/bin/sail artisan test tests/Feature/Filament/RestoreRunPreviewProductizationTest.php --compact
cd apps/platform && ./vendor/bin/sail artisan test tests/Feature/Filament/RestorePreviewTest.php --compact
cd apps/platform && ./vendor/bin/sail artisan test tests/Feature/Filament/RestoreSafetyIntegrityWizardTest.php --compact

Browser smoke:

cd apps/platform && ./vendor/bin/sail php vendor/bin/pest tests/Browser/Spec332RestoreRunWizardPreviewSmokeTest.php --compact

Formatting:

Spec 334 (nested Filament/Livewire context hardening) must be present on the branch to avoid tenantless Livewire update crashes during wizard smoke validation.
