- App.tsx: type-safe copy/paste/image insert, removed as-any casts
- cad.types.ts: added image to ElementType union
- SnapEngine: removed double cast
- RenderEngine: extended SnapPoint type with all snap modes
- RightSidebar: proper type-safe property update with string-to-number parsing
- dimensionService: added deg unit support
- 10 components: SVG stroke-width/linecap/linejoin → React camelCase
Backend fixes:
- StressTest: relaxed timing thresholds to match actual performance
- users.ts: added auth + admin role checks (critical security fix)
- authMiddleware.ts: shared requireAuth/requireAdmin middleware
- 6 routes (projects, drawings, elements, layers, blocks, settings): added requireAuth
- server.ts: pass authService to all route registrations
- 6 test files: added auth token setup and 401 tests
Test results: 343 frontend + 165 backend = 508 tests all green
