Fix nested f-string syntax error in confidence and accuracy extraction logic

[deril2605]

Purpose

This PR fixes a syntax error in the logic that formats the Confidence and Accuracy fields when building the rows list. The error was caused by an invalid nested f-string using double quotes inside another f-string. This fix replaces the inner quotes with single quotes and simplifies the conditional formatting logic to ensure proper execution.
