Import modes: update, deactivate, clean

The import mode sets what happens to products that are no longer in the price list and how existing products are updated. You set it on the supplier page in the "Import Settings" block.

1. "Update / Create (Upsert)" (default): found products are updated by barcode or SKU, new ones are created, missing ones are left as they are. This is the safest option.
2. "Update + Deactivate missing": like the first, but products that are no longer in the price list become inactive and are removed from your store. Use it if your supplier removes discontinued items from the price list.
3. "Clean import": deletes all products of the supplier and loads them again. Manual price edits and PIM links are lost. Use it only when you need to start from scratch.
