## Summary
- add the canonical admin-plane `My Findings` inbox at `/admin/findings/my-work`
- add the workspace overview `Assigned to me` signal and inbox-to-detail continuity
- add focused Pest coverage plus the full Spec 221 artifact bundle
## Validation
- `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Findings/MyWorkInboxTest.php tests/Feature/Authorization/MyWorkInboxAuthorizationTest.php tests/Feature/Dashboard/MyFindingsSignalTest.php`
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Filament/WorkspaceOverviewNavigationTest.php`
- integrated-browser smoke completed against the browser-facing `tenantatlas` runtime, including seeded positive-path and negative-path checks plus fixture cleanup
## Filament v5 Guardrails
- Livewire v4.0+ compliant
- panel provider registration remains in `apps/platform/bootstrap/providers.php`
- global search behavior is unchanged; `FindingResource` already has a View page and the new inbox is a custom page, not a searchable resource
- no destructive actions were introduced on the inbox or overview signal
- no new assets were added; the existing deploy step for `cd apps/platform && php artisan filament:assets` remains unchanged
- coverage includes the new inbox page, authorization boundaries, the workspace overview signal, and the overview CTA regression
