Pull request overview

This pull request refactors the getCommonHistoryGroupFields function to accept a single object parameter with named properties instead of 8 individual positional parameters. This improves code readability, especially for the 3 optional parameters that previously required passing undefined placeholders.

Changes:

• Updated getCommonHistoryGroupFields function signature to use object destructuring with named parameters
• Updated all 7 call sites across different history group generator functions to use the new object parameter syntax
• Updated the test file to use the new function signature
