chore: bump version to 1.0.30

Backend changes:
- Update multer configuration to accept up to 500 files per upload
- Implement batch processing (10 files per transaction) for better performance
- Add memory-efficient Sharp configuration for thumbnail generation
- Increase Express body parser limits to handle large payloads
- Add proper error handling and reporting for partial upload failures

Frontend changes:
- Update validation to allow 500 files maximum
- Implement chunked uploads (50 files per chunk) to prevent timeouts
- Add progress tracking with chunk information display
- Update error messages and translations (EN/DE)

Performance optimizations:
- Disable Sharp cache to prevent memory buildup
- Limit Sharp concurrency to 2 operations
- Use sequential read for large images
- Process files in database transaction batches
- Return detailed upload results including success/failure counts

This implementation ensures the application can handle large photo uploads
efficiently without running into memory or timeout issues.
