feat: Policy Explorer UX Upgrade (003)

Implemented MVP with all core features:
- Browse 50 newest policies on load with null filtering
- Click row to view details in slide-over sheet
- JSON detection and pretty formatting
- Search with real-time filtering
- Badge colors for policy types (Security=red, Compliance=blue, Config=gray, App=outline)
- Navigation consolidated to 'Policy Explorer'

New components:
- PolicyTable.tsx - table with badges and hover effects
- PolicySearchContainer.tsx - search state management
- PolicyDetailSheet.tsx - JSON detail view with formatting
- PolicyExplorerClient.tsx - client wrapper
- lib/utils/policyBadges.ts - badge color mapping

Updated:
- lib/actions/policySettings.ts - added getRecentPolicySettings() with null filtering
- app/(app)/search/page.tsx - converted to Server Component
- config/nav.ts - renamed Search to Policy Explorer, removed All Settings
- components/search/EmptyState.tsx - updated messaging

Tasks complete: 36/47 (MVP ready)
- Phase 1-7: All critical features implemented
- Phase 8: Core polish complete (T041), optional tasks remain

TypeScript: ✅ No errors
Status: Production-ready MVP
