Bitstream download route fails when DSpace is deployed under a custom context path

[hernanhlagos]

Describe the bug

When DSpace Angular is deployed under a custom context path (e.g. /repository), the generated bitstream download URLs are incorrect.

Instead of including the context path, the links are built as if DSpace was mounted at root /. This results in broken download links (404 Not Found).

Version(s): DSpace Angular 7.x, 9.x (tested on 7.4, 9.1, likely affects other versions)
Browser: Tested on Chrome 140, Edge 140 (same behavior)

To Reproduce

Steps to reproduce the behavior:

1. Deploy DSpace Angular with a custom context path, e.g. http://localhost:4000/repository or http://localhost:4000/repository/items/[item_id]/edit/bitstreams.
2. As an administrator, edit an Item and go to the Edit Item screen.
3. Select the Files tab.
4. Click the download icon in the Actions column (BUNDLE: ORIGINAL, TEXT, THUMBNAIL, LICENSE) (see screenshot).
5. Observe the URL of the download request.

Expected behavior

The generated download URLs should include the configured context path.
