[web] Archiving a session works, but session list in sidebar becomes stale #8493

Description

Current behavior

Archived sessions remain in the session list until page refresh

Expected behavior

Session is removed from the sidebar list after the archive request succeeds (without a page refresh)

Plugins

None

OpenCode version

1.1.20

Steps to reproduce

1. opencode serve
2. Open a project with sessions
3. Click the "archive" icon button in the sidebar for any session
4. PATCH request to server returns 200 OK
5. Session remains in the sidebar list (in fact, it moves to the top because it now has the most recent update)
6. Refresh page
7. See that the archived session is now gone, as expected
