fix(bitstream): restore item UUID in edit redirect

[amadulhaxxani]

Problem description

When editing a bitstream (from the item bitstreams page) and clicking Save or Cancel, the user is redirected to items/edit/bitstreams instead of items/<UUID>/edit/bitstreams. The item UUID is missing from the redirect URL.

Analysis

The redirect uses this.itemId to construct the URL. This value comes from:

• Route query parameters (itemId) – missing when navigating from the item bitstreams page edit button.
• Async resolution from bundle.item in ngOnInit – may not have completed or may be undefined if the link is not resolved on the Bundle model.

The edit button in item-edit-bitstream-bundle.component.html only uses [routerLink] without passing query params. The fallback logic in navigateToItemEditBitstreams() was removed previously, so navigation proceeds with undefined itemId.

Pull request overview

This PR fixes redirects after editing a bitstream so users return to the correct item bitstreams edit page (/items/<UUID>/edit/bitstreams or /entities/<type>/<UUID>/edit/bitstreams) instead of a URL missing the item UUID.

Changes:

• Pass itemId (and entityType) as query params when navigating from the item bitstreams table to the bitstream edit page.
• Reintroduce fallback logic in the bitstream edit page to resolve itemId from the owning bundle’s item link when query params are missing.
