fix: resolve archive-tab and new-workspace e2e failures (round 4)

- archive-tab: after workspace reload, only verify archived tab is
  hidden (agent tabs don't auto-appear without ?open= intent). Real-time
  archive propagation still fully verified before reload.
- new-workspace: use gotoAppShell + sidebar navigation instead of direct
  workspace URL navigation. Matches the pattern of passing tests where
  the WebSocket connection and workspace hydration complete before
  sidebar interaction.
