feat: Complete Task 6 - File Upload Backend Infrastructure

Browse Source 
Backend File Upload System:
- Implemented comprehensive multer middleware with file validation
- Created file storage service supporting local filesystem and S3
- Added upload progress tracking with real-time status updates
- Built file cleanup utilities and error handling
- Integrated with document routes for complete upload workflow

Key Features:
- PDF file validation (type, size, extension)
- User-specific file storage directories
- Unique filename generation with timestamps
- Comprehensive error handling for all upload scenarios
- Upload progress tracking with estimated time remaining
- File storage statistics and cleanup utilities

API Endpoints:
- POST /api/documents - Upload and process documents
- GET /api/documents/upload/:uploadId/progress - Track upload progress
- Enhanced document CRUD operations with file management
- Proper authentication and authorization checks

Testing:
- Comprehensive unit tests for upload middleware (7 tests)
- File storage service tests (18 tests)
- All existing tests still passing (117 backend + 25 frontend)
- Total test coverage: 142 tests

Dependencies Added:
- multer for file upload handling
- uuid for unique upload ID generation

Ready for Task 7: Document Processing Pipeline
