Detailed Description

Database logging adapter with runtime backend selection.

This adapter provides unified logging interface for database operations using the backend pattern for runtime polymorphism.

Available backends:

• common_logger_backend: Uses common_system's ILogger and GlobalLoggerRegistry (default)
• fallback_logger_backend: Uses std::cout + std::ofstream (when common_system unavailable)
• null_logger_backend: No-op backend for disabling logging

Features:

• SQL query logging with sanitization (password removal, truncation)
• Automatic slow query detection and warning
• Connection pool event logging
• Transaction logging
• Error logging with SQL state codes
• Thread-safe operation
• Runtime backend selection (no conditional compilation)
