fix: stabilize frontend — 98 TS errors to 0, align API endpoints, optimize bundle
- Fix 98 TypeScript errors across 37 files:
- Service layer double-unwrapping (subscriptionService, distributionService, gearService)
- Self-referencing variables in SearchPageResults
- FeedView/ExploreView .posts→.items alignment
- useQueueSync Zustand subscribe API
- AdminAuditLogsView missing interface fields
- Toast proxy type, interceptor type narrowing
- 22 unused imports/variables removed
- 5 storybook mock data fixes
- Align frontend API calls with backend endpoints:
- Analytics: useAnalyticsView now calls /creator/analytics/dashboard (was /analytics)
- Chat: chatService uses /conversations (was mock data), WS URL from backend token
- Dashboard StatsSection: uses real /dashboard API data (was hardcoded zeros)
- Settings: suppress 2FA toast error when endpoint unavailable
- Fix marketplace products: seed uses 'active' status (was 'published')
- Enrich seed: admin follows all creators (feed has content)
- Optimize bundle: vendor catch-all 793KB→318KB gzip (-60%)
Split into vendor-charts, vendor-emoji, vendor-swagger, vendor-media, etc.
- Clean repo: remove ~100 orphaned screenshots, audit reports, logs from root
