#### What this PR does / why we need it:
In the attachment upload modal, we previously persisted the user’s selected storage policy and group to make future uploads more convenient. However, this overlooked a common usage scenario—users often apply filters for storage policy and group in the attachment list before uploading. Persisting those previous selections could then conflict with the current filters and cause confusion. This PR removes the persistence of selected group and storage policy to avoid such mismatches.
