fix: allow win32com operations on files already open in Excel

win32com's Dispatch("Excel.Application") connects to the existing
instance, so operations like pivot create/refresh, chart --pivot,
and table --native can work with files already open in Excel.
Remove unnecessary file lock checks for these commands.
