Subject: [PATCH] Add diagnostics and logging tests - Created integration tests
 for /diagnostics/* endpoints - Added unit tests for logging functionality and
 configuration - Tests error reporting, system health, and log management -
 Covers GlobalLogger, file handlers, and error handling - Ready for future
 diagnostics endpoint implementation
