fix: enable HTML5 drag-drop on Windows (print analysis drop zone) - #15

In Tauri v2, dragDropEnabled defaults to true which causes Tauri to intercept OS-level file drops, leaving DataTransfer.files empty in the WebView2 HTML5 DragEvent on Windows. Setting dragDropEnabled: false passes file drops back to the WebView so the existing drop zone handler works as expected. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

Why
On Windows, dragging an image from File Explorer onto the Print Analysis drop zone did nothing. The drop handler never received any files because
DragEvent.dataTransfer.fileswas always empty.What changed
Set
"dragDropEnabled": falsein the Tauri window configuration (src-tauri/tauri.conf.json).By default, Tauri v2 sets
dragDropEnabled: true, which causes Tauri to intercept OS-level file drops at the WebView2 layer and handle them via its owntauri://drag-dropevent. A side effect is that the standard HTML5DataTransfer.fileslist is left empty -- so the existingon:drophandler inPhotoDropZonenever found any files to process on Windows.Disabling Tauri's interception passes the drop event back to WebView2 directly, which correctly populates
DataTransfer.filesand lets the existing handler work as intended. No frontend code changes are needed. macOS and Linux are unaffected.
