feat: compress governance operator outcomes (#253)
## Summary
- introduce surface-aware compressed governance outcomes and reuse the shared truth/explanation seams for operator-first summaries
- apply the compressed outcome hierarchy across baseline, evidence, review, review-pack, canonical review/evidence, and artifact-oriented operation-run surfaces
- expand spec 214 fixtures and Pest coverage, and fix tenant-panel route assertions by generating explicit tenant-panel URLs in the affected Filament tests
## Validation
- `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`
- focused governance compression suite from `specs/214-governance-outcome-compression/quickstart.md` passed (`68` tests, `445` assertions)
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Filament/InventoryItemResourceTest.php tests/Feature/Filament/BackupSetUiEnforcementTest.php tests/Feature/Filament/RestoreRunUiEnforcementTest.php` passed (`18` tests, `81` assertions)
