ATAS import preview stays visible while you save

On the ATAS import preview step, saving trades used to refresh your local trade list and could clear the preview or mislabel rows as duplicates. The importer now keeps a fixed snapshot of your existing trades for duplicate checks for the whole session.

You can review new vs duplicate trades, enter missing commissions, and confirm the import without the preview flashing empty or trades flipping to “already imported” while the save is still running.
