fix: Simplified Docker deployment and fixed upload path resolution

🐳 Docker Configuration Improvements:
- Simplified docker-compose.yml to use single app folder bind mount
- Removed complex data folder mapping that caused path confusion
- Updated environment variables to match entrypoint script expectations
- Streamlined deployment for better reliability

🔧 Upload System Fixes:
- Fixed path resolution issues in uploads.py for containerized deployment
- Simplified upload folder path handling to work correctly in containers
- Removed complex absolute path conversion logic that caused file placement issues
- Ensured all file operations use consistent /app/static/uploads path

📁 File Processing Improvements:
- Fixed PPTX to JPG conversion workflow path handling
- Corrected PDF processing to save files in correct container location
- Improved video conversion path resolution
- Enhanced error handling and logging for upload operations

🚀 Production Benefits:
- Eliminates 404 errors for uploaded media files
- Ensures files are saved in correct locations within container
- Simplifies development and debugging with direct app folder mounting
- Maintains data consistency across container restarts

✅ This resolves the upload workflow issues where PPTX files were not
being correctly processed and saved to the expected locations.
