Add structured logging throughout the backend: - logging_config.py: Centralized logging configuration with colored output - main.py: Enhanced startup logging showing initialization progress - init_blockchain.py: Detailed blockchain initialization logging - services.py: Election creation logging Logging features: - Emoji prefixes for different log levels (INFO, DEBUG, ERROR, etc.) - Color-coded output for better visibility - Timestamp and module information - Exception stack traces on errors - Separate loggers for different modules This helps debug: - Backend startup sequence - Database initialization - Blockchain election recording - Service operations - Configuration issues
