Don't throw error when no folder selected for import (#2188)

 ## Summary by cubic Stop throwing an error when the user cancels folder selection in the import dialog. The mutation now returns null, so cancelling the picker doesn’t show an error or disrupt the flow. <sup>Written for commit 3c2e61bc723a3ff72cc269c31f715b440fc3695b. Summary will update on new commits.</sup>   --- > [!NOTE] > Prevents erroneous failures when the user cancels the folder picker. > > - In `ImportAppDialog`, `selectFolderMutation` now returns `null` when no `path`/`name` is provided (user canceled) instead of throwing, avoiding error toasts and treating cancel as a no-op. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 3c2e61bc723a3ff72cc269c31f715b440fc3695b.
