    [SPARK-32924][WEBUI] Make duration column in master UI sorted in the 
correct order
    
    ### What changes were proposed in this pull request?
    
    Make the "duration" column in standalone mode master UI sorted by numeric 
duration, hence the column can be sorted by the correct order.

    ### Why are the changes needed?
    
    Fix a UI bug to make the sorting consistent across different pages.
    
    ### Does this PR introduce _any_ user-facing change?
    No.
    
    ### How was this patch tested?
    Ran several apps with different durations and verified the duration column 
on the master page can be sorted correctly.
    
    Closes #31743 from baohe-zhang/SPARK-32924.
