feat: implement spec 193 monitoring action hierarchy (#227)
## Summary
- codify Spec 193 as an explicit monitoring/workbench surface inventory with validator and guard coverage
- refactor the Finding Exceptions Queue, Operations landing, and tenantless operation viewer into clearer context, navigation, utility, drilldown, and focused-work lanes
- align Alerts, Audit Log, and Alert Deliveries with quiet origin-context handling while preserving calm reference surfaces and the explicit Tenant Diagnostics exception
- add focused feature coverage, guard coverage, browser smoke coverage, and the full spec artifacts for Spec 193
## Verification
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Guards/ActionSurfaceContractTest.php tests/Feature/Guards/ActionSurfaceValidatorTest.php tests/Feature/Guards/Spec193MonitoringSurfaceHierarchyGuardTest.php tests/Feature/OpsUx/OperateHubShellTest.php tests/Feature/Operations/TenantlessOperationRunViewerTest.php tests/Feature/Monitoring/FindingExceptionsQueueHierarchyTest.php tests/Browser/Spec193MonitoringSurfaceHierarchySmokeTest.php`
- `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`
- integrated-browser smoke pass over queue, operations, operation detail, alerts, audit log, and tenant diagnostics
## Notes
- Livewire v4 / Filament v5 stack unchanged
- no provider-registration changes; Laravel 11+ provider registration remains in `bootstrap/providers.php`
- no new global-search behavior was introduced
- destructive and governance-changing actions keep their existing confirmation and authorization semantics
- no new assets or migrations were added
