Realtime import progress modal could hang when a late 'progress' event
arrived after 'complete' (hide_progress nulls cur_progress, show_progress
then recreates an unmanaged modal). Guard every handler with an
importFinished flag and force-close via modal('hide')+remove()+backdrop
cleanup across company/employee/journal_entry/purchase_order/sales_*.
Also: show VAT operation İzahat (explanation) column in the selection
table and on the Journal Entry list; auto-create missing "Classification
code" records from taxCodeInfo so the Link field always resolves.
