**Import Fixes:**
- Fixed sonner.tsx to import `useTheme` from local `@/components/theme/ThemeProvider` instead of incorrect `next-themes` package
### Additional Bug Fixes and Security Improvements (October 7, 2025)
**Security Enhancements:**
- `supabase/functions/upload-image/index.ts`: Added authentication requirements for POST and GET operations to prevent unauthorized access to image uploads and status checks
- All image operations now verify JWT tokens via Supabase auth before proceeding with Cloudflare API calls
- Added TODO comments for restricting CORS to specific domains in production environments
**Performance Optimizations:**
- `src/components/upload/PhotoUpload.tsx`: Optimized session token fetching to retrieve once before polling loop instead of on every iteration, reducing unnecessary authentication calls and improving upload performance
**Enhanced Input Validation:**
- `supabase/functions/create-novu-subscriber/index.ts`: Comprehensive validation added for all fields:
- Required fields: subscriberId and email with format validation
- Optional fields: firstName/lastName (max 100 chars), phone (international format), avatar (valid URL), data (object type with 10KB size limit)
- Graceful handling of malformed JSON with proper 400 error responses instead of 500
**Error Handling Improvements:**
- `src/lib/versioningHelpers.ts`: Added `instanceof Error` checks before accessing `error.message` to prevent runtime crashes
- `src/lib/notificationService.ts`: Added safe error message extraction with fallback for non-Error objects
- All error handlers now provide user-friendly messages while maintaining detailed logging
