Allow moving bitstreams between bundles in the UI

[saschaszott]

Currently, the DSpace Angular UI only allows reordering bitstreams within the same bundle (i.e. changing the bitstream order inside a bundle). However, it is not possible to move bitstreams between different bundles of an item via the UI.

From a functional perspective, it would be very helpful if the UI also allows users to move bitstreams from one item's bundle to another (e.g. from ORIGINAL to a custom bundle).

The DSpace REST API already supports this functionality (PUT method described in https://github.com/DSpace/RestContract/blob/main/bitstreams.md#bundle), so the required backend capabilities are already in place. This enhancement would therefore mainly require integrating the existing REST functionality into the Angular UI.

This seems reasonable overall. It might not be too difficult to implement (since the REST API endpoint exists). It could just be a matter of allowing bitstreams to be "dragged" to a different Bundle in the UI.

That said, this would require a volunteer to investigate and implement.

@tdonohue I would like to work on this issue.

@Aryakoste : I'll assign it to you then. Thanks for volunteering.
