Release version 0.2.3

Improve the History tab by keeping records in chronological order, rendering them as a compact table, and allowing the Time column to toggle ascending or descending order.

Use the native Fyne table header so users can resize columns, including Detail and Log, and show only the log file name instead of the full log path.

Bump the application version to 0.2.3 and update README artifact examples plus docs/CHANGELOG.md.
