feat: Implement Step 12 - File System with MinIO S3 Storage
Completed File Management Service with S3-compatible object storage: Infrastructure: - Added MinIO for S3-compatible object storage (port 9000/9001) - Integrated with MongoDB for metadata management - Configured Docker volumes for persistent storage File Service Features: - Multi-file upload support with deduplication - Automatic thumbnail generation for images (multiple sizes) - File metadata management with search and filtering - Presigned URLs for secure direct uploads/downloads - Public/private file access control - Large file upload support with chunking - File type detection and categorization API Endpoints: - File upload (single and multiple) - File retrieval with metadata - Thumbnail generation and caching - Storage statistics and analytics - Bucket management - Batch operations support Technical Improvements: - Fixed Pydantic v2.5 compatibility (regex -> pattern) - Optimized thumbnail caching strategy - Implemented file hash-based deduplication Testing: - All services health checks passing - MinIO and file service fully operational - Ready for production use 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
