Fixed escape() function to properly escape special characters (tabs,
newlines, backslashes) in the correct order when using --bulk-insert.
The original single regex replacement could cause incorrect escaping
order. Now escaping is done in sequence: backslash first, then newline,
then tab, ensuring proper field alignment when data contains these
special characters.
Fixes issue where fields would misalign when archiving data containing
tabs, newlines, or backslashes with --bulk-insert option.
