Desktop: archiving a session from the Completed list jumps to a new session instead of selecting the next one in the list

Summary

In the desktop app's session sidebar, archiving a session from the Completed list navigates away to a brand-new, empty session screen. I expected the app to stay in the list and select the session that was directly below the archived one.

Steps to reproduce

1. Have several sessions in the Completed section of the sidebar.
2. Right-click a session that is not the last one in the list → Archive (or press A).
3. Observe which session is displayed afterwards.

Actual behavior

The main pane switches to a new/empty session screen. My place in the list is lost, and I have to scroll back and click the next session manually.

Expected behavior

After archiving, select and display the session that was immediately below the archived one within the same list — the same convention as mail clients and file managers. Suggested fallbacks:

• If the archived session was the last item in its list, select the item immediately above it.
• Only if the list becomes empty should the app fall back to a new session screen.

Why it matters

Archiving is usually done in a sweep — several finished sessions in a row. Being thrown to a new session after every single archive turns a quick cleanup pass into repeated re-navigation.
