After "Let AI fill this quote" the page re-pulls the quote's lines and
merges them with mergeItemsAfterAiRun: rows unchanged since the last load
take the server copy (so fills show), rows with unsaved changes stay as
typed, with a toast saying how many were kept. Previously onDone ran
fetchData, which replaced every row.
