Implements Spec 117 (Golden Master Baseline Drift Engine):
- Adds provider-chain resolver for current state hashes (content evidence via PolicyVersion, meta evidence via inventory)
- Updates baseline capture + compare jobs to use resolver and persist provenance + fidelity
- Adds evidence_fidelity column/index + Filament UI badge/filter/provenance display for findings
- Adds performance guard test + integration tests for drift, fidelity semantics, provenance, filter behavior
- UX fix: Policies list shows "Sync from Intune" header action only when records exist; empty-state CTA remains and is functional
Tests:
- `vendor/bin/sail artisan test --compact tests/Feature/Filament/PolicySyncCtaPlacementTest.php`
- `vendor/bin/sail artisan test --compact --filter=Baseline`
